Gold ore from the major classification is mainly for the vein gold deposits and alluvial gold deposits two types, which vein gold ore is the main case of internal geological action, mainly by volcanic, magmatic, geological action to form; alluvial gold deposits mainly by the mountain gold ore exposed in the ground, after long-term weathering, exfoliation, broken into gold sand, gold particles, gold flakes, gold froth, in the wind and water transport action gathered, deposited in the river, lake, coast, the formation of flood type, alluvial type or Coastal type alluvial gold deposits; There is another part after weathering and denudation, forming residual type alluvial gold deposits or slope accumulation type alluvial gold deposits, this kind of ore formation is generally more long time. According to the associated situation of China's gold ore types can also be divided into gold quartz veins, gold pyrite quartz veins, gold pyrite alteration granite, gold polymetallic sulphide ore vein type, gold oxide ore vein type and gold tungsten arsenic ore vein type.   Vein gold ore industrial mining grade generally in 3 ~ 5 g / ton, border grade 1 ~ 2 g / ton, alluvial gold in 0.2 ~ 0.3 g / cubic meter, border grade 0.05 ~ 0.1 g / cubic meter, but the current stage of mining gold ore in China mainly to vein gold deposits, accounting for about 75% ~ 85%.   At this stage, gold ore is widely used in jewelry, industrial, high-tech industries, etc. Because of its scarcity and non-renewable, the overall value is high. At this stage, gold ore beneficiation methods are mainly divided into four kinds: heavy separation method, flotation method , chemical separation method, and photoelectric separation method.   The re-election method is suitable for coarse-grained gold recovery, and generally belongs to the auxiliary process in gold ore beneficiation, placed in flotation or chemical sorting before as pre-selection process.   Flotation method is mainly widely used in rock deposits, the process has suction type or inflatable agitation type flotation machine for flotation.   Chemical separation method mainly has amalgamation and chlorination method, amalgamation method is mainly applicable to coarse grain monomer gold applicable, but because of its pollution, gradually be replaced, chlorination method mainly has two kinds of stirring chlorination and percolation chlorination.   The above three sorting are conventional gold ore sorting, with economic mining grade or higher than the industrial grade of gold ore, sorting cost is lower than the economic cost, but the general situation of China's gold ore rich ore less poor ore more; mining difficulty, easy to mine less difficult to mine more, most of the gold ore grade is less than 2 g / ton, belong to or lower than the critical mining grade, using the above way directly sorting, more gold ore sorting will appear below the economic mining Value.   Photoelectric sorting method grasps the pain and difficulty of domestic gold ore sorting, and uses artificial intelligence + photoelectric sorting means to enrich gold ore by pre-throwing waste to achieve higher economic mining grade, which solves the problem of low grade and high sorting cost of domestic gold ore. The working principle is mainly to crush and dissociate the original gold ore, after the artificial intelligence sorting machine to establish a multi-dimensional model of the ore, the use of AI photoelectric sorting machine technology to identify the texture, color, luster, shape, reflectivity and other comprehensive characteristics of the gold ore surface differences, after the industrial computer with artificial intelligence technology to sort out the gold ore concentrate and waste rock, so as to achieve the purpose of gold enrichment.     After the artificial intelligence ore sorting machine of the original ore, the ore particle size requirements, only the normal crushing and dissociation, particle size in 0.5cm-10cm, size with the selected particle size in 3-4 times, can be directly sorted enrichment, which throw waste tailings can be used as various types of construction, mine backfill and other materials. After the enrichment of gold ore after flotation or chemical separation method, sorting out the gold ore, pre-throwing waste reduces the processing level of the original ore, saving the processing cost of the subsequent processes.   For some gold ore below the economic mining grade, through the artificial intelligence ore sorter, can be enriched to reach the economic mining grade, enhance the use value of a large number of low-grade gold ore mine, artificial intelligence sorter is not only able to sort gold ore, for gold ore associated ore, as long as it can be broken and dissociated, can use artificial intelligence machine for sorting, enhance the comprehensive utilization rate of the mine, at the same time artificial intelligence sorter equipment The cost itself     Mingde photoelectric artificial intelligence ore sorting machine, for gold ore sorting has mature technology accumulation, can enrich gold ore under the premise of pre-throw waste tailings, and throw waste tailings gold grade is much lower than the economic mining grade.  

What is feldspar？ Feldspar is the most important rock-forming mineral in surface rocks. It is also a common type of aluminum silicate rock-forming mineral containing calcium, sodium and potassium. There are many types of feldspar minerals, including potassium feldspar, albite, anorthite, etc. Rarer feldspars also include barium feldspar, amazonite, etc. According to different crystal structures and compositions, feldspar can also be subdivided into plagioclase, microcline, orthoclase, striated feldspar and other varieties. These feldspars vary in color, form and transparency. They may be colorless, white, yellow, pink, green, gray or black, and may be transparent or translucent. Furthermore, the basic structural unit of feldspar is a tetrahedron, each of which shares an oxygen atom with another tetrahedron, forming a three-dimensional skeleton, with alkali or alkaline earth metal cations located in the large voids within these skeletons.  What is feldspar used for? Feldspar is widely used in many fields due to its unique physical and chemical properties Architectural decoration field: Feldspar has high durability and aesthetics and can be used to decorate building exteriors and indoor walls. It is not only beautiful but also has a long service life. Glass industry: Albite in feldspar can be used as a raw material for glass fiber. It has chemical corrosion resistance and high temperature resistance, and can significantly improve the quality and performance of glass materials. In addition, feldspar can also be used as a processing and forming aid for glass to improve the speed and accuracy of glass forming. Ceramic industry: Feldspar is an important ceramic raw material and can be used to make ceramic products such as ceramic tiles, pottery, and porcelain. Feldspar has high high temperature resistance and strength, which can improve the toughness and hardness of ceramic products while improving their aesthetics. Chemical industry: Feldspar is rich in aluminum and silicon elements and can be used as raw materials for manufacturing paints, coatings, fertilizers, rubber and other chemical products. In addition, feldspar can also be used as a fire retardant, filler, synergist, etc. to improve the quality and grade of chemical products. How to use feldspar? Feldspar processing technology mainly involves mining, crushing, grinding, screening and other steps. First, raw feldspar is obtained through mining, and then crushed and ground to achieve the desired particle size and shape. Next, the feldspar is sorted by particle size through screening to meet the needs of different fields. During the processing, attention must also be paid to protecting the feldspar to avoid contamination or damage. How to sort feldspar? Feldspar sorting technology is a process of classifying and purifying feldspar in raw ore according to different quality, particle size and chemical composition. Through sorting, feldspar products that meet the requirements of specific application fields can be obtained, improving resource utilization and product added value. At the same time, sorting technology can also help reduce the difficulty and cost of subsequent processing and improve production efficiency. Main methods for traditional sorting of feldspar：Hand selection: Mainly suitable for better quality ores, such as feldspar mined from pegmatite. Workers manually sort according to differences in appearance, color, crystal shape, etc., and remove impurity minerals such as plagioclase, mica, and garnet. Water washing, desliming and grading: For the feldspar in white weathered granite or feldspathic placer, impurities such as clay and fine mud are removed through water washing and desliming. Grading divides feldspar into different grades of products based on differences in particle size. Advanced Technology for Feldspar Sorting： Machine vision technology: The machine vision system replaces the traditional human eye for color sorting to achieve the separation of feldspar from gangue minerals such as muscovite and quartz. This technology has higher accuracy and stability and is suitable for automated sorting of large-scale production lines. Magnetic separation technology: Separate by utilizing the magnetic differences between feldspar and impurities such as iron oxide, mica and garnet. Magnetic separation technology can effectively remove magnetic impurities in feldspar and improve the purity of the product. Flotation technology: Based on the difference in surface properties between feldspar and gangue minerals such as mica and quartz, separation is achieved using flotation machines, flotation columns and other equipment. By adjusting the type and dosage of chemicals during the flotation process, the flotation effect can be optimized and the quality of feldspar products can be improved. Our MINGDE AI sorting machine adopts advanced machine vision technology and uses artificial intelligence methods such as deep convolutional neural network (CNN).Analyze and process material images in the field of visible light optoelectronic sorting. During the training process, multi-dimensional features of materials are automatically extracted and established through CNN local connection, weight sharing, multi-convolution kernel and other methods to establish a database. The sorting effect is far better than traditional photoelectric sorting. In short, feldspar as an important mineral resource, has wide applications in many fields. With the advancement of science and technology and economic development, the application fields of feldspar will be further expanded and deepened. At the same time, we should also strengthen the protection and rational utilization of feldspar resources to achieve sustainable development.  

The classification and use of ores are very wide. We classify them based on many factors such as the chemical composition, physical properties and industrial applications of minerals. The following are the types of metal ores and non-metallic ores that can be roughly sorted. Metal ore Metal ores are ores containing metal elements or metal compounds, and are mainly used to extract metals. Depending on the metals they contain, metal ores can be subdivided into the following categories: 1. Precious metal ores: such as gold, silver, platinum group metal ores, etc., are mainly used in the manufacture of jewelry, currency reserves and some high-tech products. 2. Non-ferrous metal ores: including copper, lead, zinc, aluminum, etc., which are widely used in wires and cables, building materials, automobile manufacturing, aircraft manufacturing, electronic products and other fields. 3. Ferrous metal ores: such as iron ore, manganese ore, and chromium ore, which are mainly used in the production of steel and other alloys. 4. Rare metal ores: such as tantalum, niobium, lithium, etc., are crucial to high-tech industries such as electronics, aerospace, and new energy vehicles. 5. Radioactive ores: such as uranium ore and thorium ore, which are mainly used in nuclear power generation and medical fields. After mining, crushing, beneficiation and refining, these ores can be refined into metals, which are processed into various products and widely used in various industries such as construction, machinery manufacturing, electronics, transportation, aerospace, etc. Non-metallic ores Non-metallic ores contain no or almost no metal elements. They either provide industrial raw materials or are used as decorative and building materials. 1. Chemical raw material ores: such as phosphate rock, potash, limestone, etc., used in the manufacture of fertilizers and chemical products. 2. Gemstones and decorative stones: such as diamonds, rubies, jade, marble, granite, etc., used in jewelry and architectural decoration. 3. Building material ores: such as gypsum, quartz sand, and limestone, used in cement, glass manufacturing and the construction industry. 4. Ceramic and refractory ores: such as kaolin and clay, used to make ceramic utensils and high-temperature resistant materials. 5. Energy minerals: such as coal, oil, and natural gas. Although they do not strictly belong to the traditional mineral classification, they are also important natural resources and are mainly used for energy supply. In addition to being used as a building material, it is also used to manufacture chemicals, medicines, cosmetics, ceramic products, glass products, etc. It is also widely used in agriculture, environmental protection and high-tech industries. In summary, ores are various and have a wide range of uses. From metal ores to non-metallic ores, from energy ores to construction ores and chemical raw material ores, they all play an important role in their respective fields. The mining and utilization of ores is one of the foundations of modern industrial society. However, the mining process needs to consider environmental protection and sustainable development. With the advancement of science and technology and the development of industry, human demand for ores will continue to increase, and the mining and utilization of ores will become more efficient and environmentally friendly. In order to make full use of various metal and non-metallic ore resources, suitable mineral processing technology is selected for separation in combination with the physical and chemical characteristics of the ore. At present, the common mineral processing methods are mainly the following: Flotation: It is a method of separation by treating the physical and chemical properties of the ore surface to make the minerals selectively attach to bubbles. In the process of mineral processing, especially in the treatment of non-ferrous metal ores (such as copper, lead, zinc, sulfur, molybdenum, etc.), flotation is widely used. In addition, some ferrous metals, rare metals and non-metallic ores (such as graphite ore, apatite, etc.) can also be treated by flotation. Gravity separation: It is a method of separation based on the relative density (also called specific gravity) of minerals. By applying fluid dynamics and various mechanical forces in a moving medium (such as water or air), the concentrators of different densities can create suitable loose stratification and separation conditions, thereby achieving the separation of mineral particles of different densities. Magnetic separation: It is a method of separating ores by using the magnetic difference of minerals to generate different forces in the magnetic field of the magnetic separator. It is mainly used for the separation of ferrous metal ores (such as iron, manganese, and chromium), and can also be used for the separation of non-ferrous metal and rare metal ores. Electrostatic separation: It is a separation method based on the difference in the electrical conductivity of minerals. By placing the minerals in a high-voltage electric field, the electrostatic force acts differently due to the different electrical conductivity of the minerals, thereby achieving the separation of minerals. This method is mainly used for the separation of rare metals, non-ferrous metals and non-metallic ores, especially in the separation of sub-mixed coarse concentrates, such as scheelite and cassiterite, zircon, tantalite and niobium ore. Chemical beneficiation: It is a beneficiation technology that uses chemical methods to change the mineral composition and then enriches the target components through other methods. For example, copper ore containing malachite can be leached with dilute sulfuric acid to convert malachite into copper sulfate solution. By replacing the copper ions in the solution with iron filings, metallic copper (sponge copper) can be obtained. Chemical beneficiation is one of the effective methods for processing and comprehensively utilizing some poor, fine, and impure mineral raw materials that are difficult to be selected. It is also one of the important ways to make full use of mineral resources, solve the problems of wastewater, waste residue, and waste gas treatment, realize waste recycling, and protect the environment. Microbial beneficiation: also known as bacterial beneficiation, is a beneficiation method that uses microorganisms such as iron-oxidizing bacteria, sulfur-oxidizing bacteria, and silicate bacteria to remove iron, sulfur, silicon and other elements from ores. By using iron-oxidizing bacteria to oxidize iron, sulfur-oxidizing bacteria to oxidize sulfur, and silicate bacteria to decompose silicon in bauxite, the purpose of desulfurization, iron removal and silicon removal can be achieved. In addition, microbial beneficiation can also be used to recover metals such as copper, uranium, cobalt, manganese, and gold. https://www.mdoresorting.com/mingde-ai-sorting-machine-separate-phosphorite-ore Photoelectric beneficiation: It is a beneficiation method that uses the physical characteristics of the ore to be beneficiated and the gangue to identify and sort. It uses a combination of machinery and electricity to separate minerals by imitating the action of hand selection. It uses the differences in the reflection and transmittance of light of different minerals, such as color, texture, shape, gloss, spots, density and other characteristic differences for identification and sorting. The ore is mainly separated after passing through the feeding system, photoelectric system, electric control system and sorting system. As a leader in the photoelectric mineral processing industry, Mingde Optoelectronics has launched a series of equipment, involving five series and more than 20 types of equipment, mainly artificial intelligence sorting machines, ore color sorting machines, mineral sand sorting machines, X-ray intelligent sorting machines, foreign body removal robots and other products. At present, it is widely used in metal and non-metallic minerals such as quartz, potassium feldspar, calcite, calcium carbonate, dolomite, fluorite, talc, wollastonite, bauxite, pegmatite quartz, limestone, calcium oxide, sponge titanium, silicon slag, gold mine, pebbles, phosphate rock, silica, brucite, tungsten tailings, coal gangue, coal-bearing kaolin, etc.!

From 2010 to 2019, more than 200 new gold, copper, zinc, nickel, and copper mines entered commercial production, with an estimated total ore production of 22 billion tons. The lead time from initial discovery to production varies for each mine, depending on a variety of factors, including product and mine type, geographic location, partnership history, government and community needs. The average time from discovery to production for the world's 35 largest mines is 16.9 years, with the shortest being 6 years and the longest being 32 years. In order to avoid large data deviations, some mines are not included in the calculation of the time required for top mines, mainly because the projects were abandoned after the initial discovery. (Note: Data as of March 2020) Many factors affect the time it takes to deliver a mine The average exploration and research time for the world's 35 top mines is 12.5 years, almost three-quarters of the total time invested. Mines that spend the longest time in this stage usually experience multiple changes in ownership and research revisions. Generally speaking, top mines enter the mine construction phase 1.8 years after the feasibility study is completed. Ideally, construction can begin shortly after the feasibility study is completed; but for some mines, it takes another 3 to 5 years before construction, partly because they want to continue to increase reserves before construction, or face problems such as mining permits, licenses, funding and community protests. Of the 35 top mines, 20 mines take less than or equal to the average time of 16.9 years, among which mines in Peru have the shortest delivery time, with about four-fifths of the mines taking an average of 13 years. The Las Bambas copper mine in Apurimac has been in commercial production since 2015, when a large amount of porphyry copper was discovered in 2005 (skarn copper was discovered earlier). It is the mine with the shortest delivery time and currently ranks third in Peru in ore production. Australia has opened two mines in recent years, with an average time of 10 years. The Gruyere JV gold mine in Western Australia is a 50-50 joint venture between Gold Fields Ltd. and Gold Road Resources Ltd. It took only six years from the discovery of gold in 2013 to commercial production in 2019. Although there are many deeper deposits that have been put into production, Australia's deposits tend to be near-surface oxides that are easier to explore and develop. Although Australia does not have a fully integrated federal licensing system, the official assessment of exploration and mining is much faster than in other developed countries. As noted in a 2015 study prepared for the U.S. National Mining Association, evaluations of exploration plans and mining proposals in Western Australia were completed in just 30 working days. Environmental impact assessments (EIA) are completed by the applicant and submitted to the relevant agencies for evaluation, shortening the application process. Fifteen mines exceeded the average lead time. Chile topped the list. The country's three mines had long lead times during this period, averaging 23.7 years. Mexico followed with two mines, averaging 17.5 years. Canada and Russia both approved four mines for production during this period, and both had two mines that took longer than average: two Canadian mines with an average lead time of 23.5 years, and two Russian mines with an average lead time of 27.5 years. Russia’s Bystrinskoye copper mine took 32 years from its discovery in 1986 to commence operations in 2018. Like Australia, Canada uses a streamlined permitting process and timeline, but the permitting process can involve extensive community collaboration and environmental requirements that can lead to significant delays. Canada’s Rainy River and Dublin Gulch mines took 22 and 25 years to complete, respectively. Ontario’s Rainy River mine is owned by Rainy River Resources Ltd., which chose to continue exploration and feasibility work in the area when it was unable to finance mine development. New Gold Inc. acquired the mine in 2013 and has conducted the latest feasibility study, permit application, testing and construction. Victoria Gold also revised its feasibility study for its Dublin Canyon mine several times between 2011 and 2016, subsequently securing financing and commencing construction shortly thereafter. As a result, the average time from feasibility study completion to production for both mines was only 2.5 years. Most new mines are open pit mining, and copper mines require longer lead times Of the 35 top mines counted, 31 are open pit mines, with varying ore production capacities and mining cycles. The Las Bambas copper mine has an annual production capacity of 51 million tons of ore, and it took 10 years from discovery to production. In contrast, the Bystrinskoye copper mine, with an annual production capacity of 10 million tons, has a delivery period of 32 years. The average ore production capacity of the top open pit mines is 19.1 million tons/year, and the average delivery time is 17.4 years. Only two mines have both open pit and underground mining, and both mining methods contributed to production capacity during the trial mining period. The Kibali gold mine in the Democratic Republic of Congo and the Sukari gold mine in Egypt have lower production capacities, with annual ore production of 7.2 million tons and 12.3 million tons, respectively, and delivery cycles of 15 years and 12 years, respectively. Some open-pit mines, such as Oyu Tolgoi and Yuji River in Mongolia, plan to increase underground mining in the near future. There are two other pure underground mining mines, Carrapateena in South Australia and New Afton in British Columbia, Canada, both of which have low production capacity of only 4 million tons of ore per year and an average delivery time of 13 years. Of the 35 new mines, 23 are gold mines (accounting for two-thirds of the total), 10 are copper mines, and 2 are nickel mines. Among them, the average delivery time for gold mines is 15.4 years and that for copper mines is 18.4 years. The difference between the two is mainly due to the longer exploration and feasibility study time for copper projects, which is an average of 2 years longer than that for gold projects. One reason is that, at least in the exploration stage, the availability of funds for gold projects is better than that for copper projects. This is supported by exploration data from the past 10 years. The data shows that the ratio of grassroots exploration to late-stage exploration budgets for copper and gold mines is an average of 1:1.8, which reflects the better funding supply for gold exploration. In addition, gold prices have been more resilient than copper prices over the past 10 years, which has eased capital flows for gold mines. In addition, the construction time of copper mines is also one year longer than that of gold mines on average.

Brucite, also known as magnesia, is a hydroxide ore. Its main component is magnesium hydroxide. It is one of the minerals with the highest magnesium content in nature.Brucite is a rare and precious magnesium-rich non-metallic mineral. It belongs to the trigonal crystal system and has a variety of appearances. It is usually flaky or fibrous aggregates. It is white, light green or colorless in color. It has a glassy luster on the fracture, a pearly luster on the dissociation surface, a silky luster on the fibrous one, a flexible thin sheet, and a brittle fibrous one. Brucite is a layered hydroxide that is widely distributed in nature and is widely distributed. It is mainly distributed in countries and regions such as China, Canada, and the United States. In addition, brucite mines are also distributed in Russia, North Korea, Norway and other countries. Canada and the United States are among the world's major producers of brucite. Canada's brucite is mainly distributed in Ontario, Quebec and other places, while the United States' brucite resources are mainly distributed in Nevada, Texas and other places. China's brucite resources are mainly distributed in the western region, such as Xinjiang, Qinghai, Tibet, Sichuan and other provinces and cities according to sedimentary strata. In addition, some brucite resources are also distributed in Northeast China, North China, Central China and other regions. Specifically, the total proven reserves of brucite resources in China have exceeded 25 million tons, among which Fengcheng, Liaoning, Ji'an, Jilin, Ningqiang, Shaanxi, Qilian Mountains, Qinghai, Shimian, Sichuan, Xixia, Henan and other places are important brucite production areas. In particular, Fengcheng, Liaoning, has the richest brucite resources in China, with reserves of up to 10 million tons. The proven reserves of brucite in Ningqiang, Shaanxi are 7.8 million tons; the proven reserves of brucite in Ji'an, Jilin are 2 million tons. Judging from the ore quality, scale and mining conditions of brucite, Liaoning Province has the best brucite resources in China. The brucite ore in Kuandian is close to the theoretical mass of brucite (%): MgO 66.44, H2O 29.00, SiO2 0.80, Al2O3 0.21, Fe2O3 0.73. Brucite has a variety of uses and applications, from industrial processes to environmental and technical applications. The following are some of the main uses of brucite: (1)  Extraction of magnesium and magnesium oxide The magnesium oxide content in brucite ore is high and has few impurities; the decomposition temperature is low; the volatile matter produced when heated is non-toxic and harmless, so magnesium and magnesium oxide and other products can be extracted from brucite. (2) Dead-burned magnesia Dead-burned magnesia made from brucite has the advantages of high density (greater than 3.55g/cm3), high refractoriness (greater than 2800℃), high chemical inertness and high thermal shock stability. It is widely used in the production of key parts such as furnace linings and furnace bottoms, especially in the steel and non-ferrous metal smelting industries. (3) Light magnesium oxide Light magnesium oxide is extracted from low-grade brucite rock by chemical methods. (4) Fused periclase It is a special pure product required by high-tech electronic products. The periclase aggregate refined by brucite by electric fusion has high thermal conductivity and good electrical insulation, and the product life is increased by 2~3 times. (5) Chemically pure magnesium reagent Mainly use the electric heating method to extract metallic magnesium and prepare chemically pure reagents such as MgCl2, MgSO4, and Mg(NO3)2. At the same time, it can be used to make high corrosion resistance agents and is widely used in the electroplating industry. (6) Reinforcement materials Bruceite can be used as a substitute for chrysotile in some fields, and is used in mid-range thermal insulation materials such as microporous calcium silicate and calcium silicate board. The basic formula is: diatomaceous earth, lime slurry, water glass, bruceite. The content of bruceite is 8%~10%. The product has high whiteness, beautiful appearance and low bulk density. At the same time, due to the repeatability, corrosion resistance, high hardness and good mechanical strength of brucite, it can be used as an additive to improve the strength and hardness of cement and enhance the durability of concrete. In addition, brucite can also slow down the gel phase generation rate of concrete, thereby delaying the degradation process of the structure. (7) Papermaking filler Brucite has high whiteness, good flaking, strong adhesion and poor water absorption. Using it in combination with calcite as a papermaking filler can change the papermaking process from acid method to alkali method and reduce the pollution of slurry water. (8) Flame retardant As a fibrous variant of brucite, fibrous brucite contains about 30% of crystal water and has a low decomposition temperature (450℃, static about 350℃). It is widely used in flame retardant products with its good heat resistance and flame retardancy. (9) Environmental protection application Due to its composition characteristics, brucite presents moderate alkalinity and can be used as an acidic wastewater neutralizer. It is used to purify acidic substances in wastewater and waste gas, effectively reduce pollutants such as acid rain and acidic waste gas, and thus protect the environment. In the process of neutralizing acidic substances, brucite also has a certain buffering capacity. (10) Water treatment Brucite also plays an important role in the field of water treatment. It can be used to remove hardness ions in water, prevent the formation of scale, and protect water treatment equipment. In addition, brucite can also be used for deoxygenation, adjusting the pH value of water and buffering water quality, thereby improving and optimizing water quality. In general, brucite has a wide range of uses, covering many fields such as construction, metal smelting, chemistry, water treatment, medicine, environmental protection and food industry. In order to improve the utilization value of brucite, we generally use brucite of different grades. Generally speaking, brucite is used as a raw material for magnesium salts, basic magnesium salts, magnesium oxide and other products, and the grade of brucite is relatively high. In some specific applications, such as making refractory materials and flame retardants, the grade requirements for brucite may be relatively low. In order to improve the grade of brucite, we can use crushing, dissociation and sorting to sort out the associated minerals in brucite to achieve the purpose of improving the grade of brucite. Common associated minerals in brucite are mainly serpentine, calcite, dolomite, magnesite, magnesium silicate minerals, periclase, diopside and talc. Specifically, serpentine in the associated mineral is a hydrated magnesium silicate mineral, usually yellow-green or dark green, with a glassy or silky luster. Calcite is a calcium carbonate mineral with a glassy luster and low hardness. Dolomite is a carbonate mineral, similar to calcite, but with a higher magnesium content in its chemical composition. Magnesite is a magnesium carbonate mineral with a glassy luster and low hardness. By taking advantage of the surface feature differences between its associated minerals and brucite, we use photoelectric sorting equipment for sorting, which can effectively remove most of the dissociated associated minerals, improve the grade of brucite ore, and create higher economic value for mining companies. For some brucite mining companies, after long-term mining, there is no good sorting method in the particle ore stage, resulting in about 30~40% of the concentrate with a grade of more than 60 in the tailings pond. With the development of artificial intelligence and photoelectric mineral processing technology in recent years, the technical level and equipment maturity have been widely recognized by the market and applied in the sorting of brucite tailings. In particular, Mingde Optoelectronics' artificial intelligence sorting equipment can accurately identify associated minerals such as brucite, serpentine, and dolomite, and sort them by taking pictures, training, learning, and modeling the ore to be selected. MINGDE Optoelectronics is an enterprise focusing on ore sorting technology. The artificial intelligence sorting machine developed by it is applied to the sorting process of brucite. The equipment uses advanced image recognition technology and artificial intelligence algorithms to efficiently and accurately grade the quality of brucite, remove impurities, and improve the quality of the original ore. In summary, MINGDE Optoelectronics' artificial intelligence sorting machine plays a key role in the sorting of brucite. It optimizes the traditional mineral processing process through intelligent technology, improves the sorting accuracy and efficiency, and contributes to the sustainable use of resources.

Overview of photoelectric sorting technology Photoelectric sorting technology is a technology that uses optical principles to automatically identify and classify materials. It detects the optical properties of materials, such as color, gloss, transparency, etc., through photoelectric sensors, and then determines whether it has the required characteristics through preset intelligent algorithms, and performs corresponding separation processing. This technology is widely used in industries such as mining, agriculture, food processing, and waste material recycling, especially in improving sorting efficiency and accuracy, reducing labor intensity, and reducing environmental pollution. Working principle of photoelectric sorting technology The working principle of photoelectric sorting technology involves several key components: light source system, sensor system, signal processing system, and execution system. First, the light source system provides light of different wavelengths to illuminate the material to be detected, so that the reflected light presents different colors. The sensor system, usually a linear array CCD sensor, captures these lights and converts them into electrical signals. The signal processing system processes these electrical signals, analyzes the characteristics of the materials through image processing algorithms, and classifies them according to preset standards. Finally, the execution system sorts the sorted materials, usually by high-speed airflow or robotic arms to exclude defective products and retain high-quality products. Application of photoelectric sorting technology in mining In the mining field, photoelectric sorting technology is mainly used for pre-sorting of ore to improve the overall grade of ore and reduce the cost of subsequent processing. For example, in the process of phosphate ore sorting, photoelectric sorting technology can effectively identify and remove low-grade ore and debris, thereby improving the efficiency of mineral processing and reducing energy consumption. In addition, this technology can also be used to process phosphate resources with fine particle size and complex embedded morphology, so that resources that were originally difficult to develop and utilize economically and efficiently can be fully utilized. Advantages and challenges of photoelectric sorting technology The advantages of photoelectric sorting technology lie in its high precision, high efficiency and environmental protection characteristics. It can complete the sorting of a large number of materials in a short time without adding chemical reagents, reducing pollution to the environment. However, the technology also faces some challenges, such as adapting to the sorting needs of more types and complex ore structures, improving the stability and anti-interference ability of the system, and reducing costs. Future development of photoelectric sorting technology With the continuous advancement of technology, photoelectric sorting technology is expected to further improve recognition accuracy and stability in the future, expand the scope of application, and play a greater role in mining and other fields.

Overview Ore pretreatment and enrichment are key links in improving the utilization efficiency of mineral resources, especially in the current situation of increasingly tight global mineral resources, its importance is becoming more and more prominent. Pretreatment mainly includes crushing, grinding, screening, primary selection and other processes, aiming to improve the properties of ore and prepare for further beneficiation processes. Enrichment is to separate valuable minerals from ore by physical, chemical or biological methods to improve their grade and recovery rate. Research progress of pretreatment technology The development trend of pretreatment technology is to improve efficiency and reduce costs while paying attention to environmental protection and sustainability. The high-pressure roller mill pretreatment technology in the crushing stage improves the dissociation degree and grinding efficiency of the ore through high pressure and slow relative movement. The pre-waste technology in the primary selection stage refers to separating a part of waste rock or low-grade ore in the early stage of ore processing to reduce energy consumption and cost in subsequent processing. For example, by pre-selecting and discarding waste, the amount of ore entering the subsequent process can be reduced, saving a lot of subsequent process costs. At the same time, the pre-discarded waste tailings can be used as building aggregates and mine backfill without grinding, which has certain economic value and environmental value. Through pretreatment and pre-selection, the grade of ore can be improved, the amount of ore entering the mill can be reduced, and the tailings can be discarded in advance, thereby improving resource utilization and reducing energy consumption and environmental pollution. Ore photoelectric sorting technology is an important branch of the current ore sorting field. It uses different physical properties of ore, such as color, texture, density, etc., to achieve effective ore sorting, which is of great significance for ore pretreatment. Research progress of enrichment technology Ore enrichment technology can increase the content of useful components in ore, thereby improving resource utilization. For example, through pretreatment and enrichment technology, the original low-grade ore can be made usable, the loss of mineral resources can be reduced, the import volume of mineral resources can be reduced, and the resource utilization of low-grade ore and stockpiled waste can be realized. Ore enrichment can also reduce the processing cost and energy consumption of ore. For example, through pre-enrichment technology, the amount of subsequent grinding-flotation ore processing can be reduced, production costs can be reduced, and the economic benefits of the enterprise can be improved. At the same time, ore enrichment technology also has extremely high environmental and social benefits. In terms of environmental effects, through scientific ore enrichment and ore deposit analysis, environmental pollution can be reduced, the ecological environment can be protected, resources can be recycled, and the service life of resources can be extended. In terms of social benefits, the innovation of ore enrichment technology has promoted the upgrading of the mining industry. The development of intelligent mineral processing technology, such as intelligent mineral processing and intelligent monitoring, has improved the efficiency and accuracy of mineral processing, reduced labor costs, and promoted the transformation of the mining industry towards high efficiency and environmental protection. On the other hand, through ore enrichment, employment opportunities can be increased and the living standards of local residents can be improved. Among them, photoelectric sorting is particularly representative in ore enrichment. By analyzing the surface characteristics of the ore to be processed, the ore is preliminarily sorted, thereby realizing pollution-free and efficient intelligent sorting. Photoelectric sorting has the advantages of high efficiency, low cost, and green environmental protection. It can save freight and reagent costs in the flotation link and extend the service life of the tailings pond. In addition, the mining boundary grade can be reduced and the amount of recoverable resources can be increased. https://www.mdoresorting.com/mingde-ai-sorting-machine-separate-quartzmicafeldspar-from-pegmatite Mingde Optoelectronics Technology Co., Ltd. is the first to introduce artificial intelligence and big data technology in the field of visible light photoelectric sorting, which broadens the adaptability of the machine and allows the photoelectric sorting machine to sort more types of ores. The machine uses a gigapascal camera to further improve the sorting accuracy of the machine, and the introduction of heavy-duty machines enables the machine to process 100 tons per hour. These pioneering measures make our machines more suitable for mining companies and make ore sorting better and faster. Conclusion In summary, ore pretreatment and enrichment technology plays an important role in improving the utilization efficiency of mineral resources, reducing production costs, and promoting environmental protection and sustainable development. With the continuous emergence and application of new technologies, pretreatment and enrichment technology will continue to develop in the direction of high efficiency, environmental protection, and low cost, and contribute to the sustainable development of the mining industry.

Potassium feldspar is a common feldspar mineral with the chemical formula NaAlSi3O8, belonging to the category of sodium aluminum silicate. It usually appears as glassy crystals and can be colorless, white, yellow, red or black. Potassium feldspar is most common in pegmatites and felsic igneous rocks such as granite, and is also found in low-grade metamorphic rocks and some sedimentary rocks. The hardness of potassium feldspar is about 6-6.5, the density is between 2.61-2.64 g/cm³, and the melting point is about 1100℃. Its theoretical chemical composition is Na2O: 11.8%, Al2O3: 19.4%, SiO2: 68.8%, but this theoretical value is difficult to achieve in nature. The classification of potassium feldspar usually based on its chemical composition and crystal structure. According to the chemical composition, potassium feldspar can be divided into different subspecies, such as albite, oligoclase and bytownite. According to the crystal structure, it can be divided into monoclinic system and triclinic system. These classifications are instructive for understanding the physical and chemical properties of potassium feldspar and its application in industry. Potassium feldspar plays an important role in the ceramic industry. It can be used as a flux, a ceramic body ingredient and a glaze. Before firing, potassium feldspar can reduce the drying shrinkage and deformation of the body, improve the drying performance and shorten the drying time. During firing, it can be used as a flux to reduce the firing temperature and improve the light transmittance of the body. potassium feldspar is also one of the important raw materials in the glass industry. It can increase the alumina content in the glass mixture, reduce the melting temperature, and adjust the viscosity and chemical composition of the glass. In addition, potassium feldspar is also used in the chemical industry, abrasives and tools, welding rods and other industries. For example, it can be used as a raw material for enamel, the main raw material for refractory materials, and as a filler in detergents, toothpaste, cosmetics and other industries. The purity of potassium feldspar directly affects its application effect in industrial production. For example, in the ceramic industry, high-purity potassium feldspar can significantly reduce the firing temperature and improve the quality and performance of the product. Therefore, accurately judging the purity of potassium feldspar is of great significance to ensure product quality and production efficiency. The determination of potassium feldspar purity usually involves the following aspects: Chemical composition analysis: Through chemical analysis methods such as ICP, XRF, AAS, etc., the main components of potassium feldspar, such as SiO2, Al2O3, Fe2O3, TiO2, K2O and Na2O, can be accurately determined. The content of these components directly reflects the purity of potassium feldspar. Physical property test: Including tests of physical properties such as hardness, density, melting point, etc., these properties can also indirectly reflect the purity of potassium feldspar. Mineral composition analysis: Through methods such as X-ray diffraction (XRD), the mineral type and content of potassium feldspar can be determined, which is also a method to judge purity. The main method of impurity separation Flotation method: By adding different flotation agents, the surface properties of potassium feldspar and other impurity minerals are changed, thereby achieving separation. Magnetic separation: Separate iron-containing impurities from potassium feldspar by using magnetic differences. Chemical impurity removal technology: Dissolve and remove impurities in the ore by acid washing and other methods.

Wollastonite surrounding rocks are divided into two types: marble type and skarn type. Among them, skarn type is mainly lens-shaped, cystic, irregular banded, etc., among which wollastonite generally has high iron impurities, and the gangue is mainly garnet, diopside, calcite and quartz. Garnet and diopside are separated by strong magnetic separation, and calcite and quartz are separated by flotation. The marble type is more complex, mainly in agglomerate and cystic shapes. Its wollastonite is distributed in flower and worm strips, with low iron content. The gangue is mainly calcite and quartz and a small amount of diopside. This type of ore is mainly separated by flotation to separate calcite and quartz. Wollastonite ore dressing and purification method At present, there are mainly manual selection, flotation, single magnetic separation, magnetic separation-flotation (electrical separation) for wollastonite separation. The purpose of wollastonite separation is mainly to reduce the iron content and separate calcite and waste rock. Hand selection mainly involves manually selecting rich ores or manually selecting rich wollastonite through conveyor belts. It is mainly suitable for ores with high wollastonite content. Flotation mainly involves separating wollastonite and calcite based on their different physical and chemical properties. It can also remove a large amount of iron impurities and improve the grade of wollastonite. Single magnetic separation mainly involves using weakly magnetic minerals such as garnet and diopside in the original ore. Wollastonite is not magnetic. Wollastonite is separated from other gangues through dry or wet strong magnetic separation technology. It can also remove a large amount of iron-containing ores and improve the overall grade. Magnetic separation-flotation is mainly suitable for the treatment of low-grade wollastonite. First, weakly magnetic ores are separated through magnetic separation, and then wollastonite is separated from quartz and calcite through flotation. The latest sorting method for wollastonite ore dressing - artificial intelligence photoelectric sorting Through physical sorting, the surface characteristics of wollastonite, calcite, and miscellaneous stones are used for sorting. Before entering flotation or magnetic separation, the raw ore is crushed and washed before entering the artificial intelligence sorting machine. Artificial intelligence photoelectric sorting uses the surface characteristics of wollastonite, calcite, quartz, garnet, and miscellaneous stones for sorting. The main surface characteristics of the sorting are color, color, texture, shape, etc., and the data model is established through artificial intelligence. The purpose of accurately sorting out wollastonite and associated stones is achieved. Artificial intelligence ore sorting machines are different from traditional photoelectric color sorters. Traditional photoelectric color sorters can only sort by color differences. For example, when the associated quartz or other colors are close to wollastonite waste rocks, the color sorter cannot accurately sort out wollastonite. Only artificial intelligence ore sorting machines integrate the multi-dimensional characteristics of good and bad materials in the raw ore, establish a sorting model, and achieve final sorting accuracy and low carryout of good and bad materials through artificial intelligence technology. https://www.mdoresorting.com/mingde-ai-sorting-machine-separate-quartzmicafeldspar-from-pegmatite Project Advantages Artificial intelligence can completely replace manual selection in the application of wollastonite. If the dissociation degree of wollastonite is good, the artificial intelligence machine can directly sort out wollastonite and tailings, which has the advantages of high efficiency, good effect and low cost. The cost is mainly the one-time equipment purchase cost and the subsequent equipment power supply cost. If the dissociation degree is average, the artificial intelligence machine can also sort out the wollastonite with good grade, or discard the useless waste rock, which can directly reduce the amount of ore entering magnetic separation or flotation, save the cost of magnetic separation and flotation, and reduce the processing level of tailings. In particular, Mingde Optoelectronics Artificial Intelligence Sorting Machine has been widely used in various ore sorting fields at this stage, not only in wollastonite. As long as there are ores with visible surface differences, they are within the sorting range of artificial intelligence sorting machines. The equipment has withstood the test of various industrial and mining enterprises in terms of technical maturity and actual application effect.

As we all know, mineral resources are the pillar of national infrastructure. During the mining process, most ores exist in the state of mineral and gangue coexistence. Only after a series of processing procedures can usable minerals be obtained. Before the ore can be effectively used, it needs to be crushed and dissociated, and then enriched by the corresponding mineral processing method. The so-called dissociation degree of a certain mineral is the ratio of the number of particles of the mineral monomer dissociated to the sum of the number of intergrowth particles containing the mineral and the number of particles of the mineral monomer dissociated. First, the block ore particles change from large to small, and various useful minerals are dissociated by reducing the particle size. First, in the crushing process, some of the various minerals that were originally intergrowthed together crack along the mineral interface and become particles containing only one mineral, which we call monomer dissociated particles, but there are still some small mineral particles that contain several minerals intergrowthed together, which are called intergrowth particles. Over-crushing mainly refers to the use of excessive grinding to achieve the full dissociation of useful minerals. In this process, more fine particles that are difficult to select are produced, that is, the phenomenon of "over-crushing" occurs. Over-crushing not only affects the grade and recovery rate of the concentrate during the selection process, but also increases the consumption of the grinding and selection process due to unnecessary crushing, resulting in increased beneficiation costs. The main hazards of over-crushing are: an increase in useful fine particles that are difficult to recover, low concentrate grade and recovery rate, increased machine loss, reduced unit time capacity, and increased useless power consumption of crushed ore. From the perspective of mineral structure, except for a few extremely coarse-grained ores that can obtain a considerable number of monomer dissociated particles after crushing, most ores must be ground to obtain a relatively high degree of dissociation. Ore crushing and grinding are too coarse and the degree of dissociation is insufficient, and too fine will cause equipment wear and increased consumption. Too coarse or too fine will lead to low concentrate grade and recovery rate. Therefore, appropriate grinding fineness is a necessary condition for achieving good separation of useful minerals and gangue minerals. Mineral processing workers should pay attention to the selection of crushing processes and equipment, strictly control the operating conditions, and strictly control the grinding fine powder within the optimal range determined by the mineral processing test. After some ores are crushed, there will be a certain proportion of low-economic-grade tailings or waste rocks with good dissociation. If such ores enter the subsequent grinding, it will directly affect the concentrate recovery and power consumption cost. Some concentrators adopt the method of early disposal and early selection to discard these useless tailings, which can not only release the production capacity of the concentrator, but also reduce the discharge of tailings after fine grinding, reduce solid mineral waste, and extend the service life of the tailings pond. As a company specializing in the research and development and production of ore sorting equipment, the photoelectric mineral processing products launched by MINGDE Optoelectronics are mainly used in the pre-sorting and pre-discarding of lump ores. According to the different degrees of dissociation of the ore, it can be used for ore sorting within the range of 0.3-15cm; it is suitable for sorting ores with different characteristics such as color, texture, texture, shape, gloss, shape, density, etc. The types of ores currently used by the equipment include fluorite, talc, wollastonite, calcium carbonate, gold mine, brucite, magnesite, silicon slag, pebbles, silica, phosphate rock, coal gangue, sponge titanium, monocrystalline silicon, lithium mica, spodumene, barite, pegmatite, tungsten tailings, coal-based kaolin and other minerals.
