Wollastonite wall rocks are divided into marble type and skarn type. The skarn type is mainly lenticular, vesicular and irregular banded. The iron impurities in the wollastonite are generally high. 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 relatively complex, mainly in the form of lumps and sacs. The wollastonite is distributed in the form of flowers and worm stripes, with low iron content. The gangue is mainly calcite and quartz and a small amount of diopside. This type of mineral is mainly separated by flotation, and calcite and quartz are separated. Wollastonite Beneficiation and purification method of wollastonite At present, the separation of wollastonite mainly includes manual separation, flotation, single magnetic separation, magnetic separation flotation (electric separation). The purpose of wollastonite beneficiation is mainly to reduce iron content and separate calcite and waste rock. Manual separation mainly refers to manual selection of rich ore or manual selection of rich ore wollastonite through conveyor belt, which is mainly applicable to ores with high wollastonite content. Flotation is mainly based on the difference of physical and chemical properties on the surface of wollastonite and calcite. Flotation can effectively separate them, remove a large number of iron impurities, and improve the grade of wollastonite. Single magnetic separation mainly uses weak magnetic minerals such as garnet and diopside in the raw ore, and wollastonite is not magnetic. Through dry or wet strong magnetic separation technology, wollastonite and other gangue can be separated, which can also remove a large amount of iron ore and improve the overall grade. Magnetic separation flotation is mainly applicable to the treatment of low-grade wollastonite. First, weakly magnetic ores are separated by magnetic separation, and then wollastonite is separated from quartzite and calcite by flotation. The latest separation method of wollastonite beneficiation - artificial intelligent photoelectric separation Through physical separation, wollastonite, calcite, miscellaneous stone and other surface characteristics are used for separation. Before flotation or magnetic separation, raw ore is crushed and washed before entering the artificial intelligent separator. Artificial intelligence photoelectric sorting uses surface features such as wollastonite, calcite, quartz, garnet seed stone, and miscellaneous stone to sort, judge the difference of various surface features such as color, color, texture, and shape, and establish a data model by means of artificial intelligence. To achieve the goal of precise separation of wollastonite and associated stone. The artificial intelligent ore separator is also different from the traditional photoelectric color separator. The traditional photoelectric color separator can only separate by color difference. For example, when the associated quartz or other colors are close to the waste wollastonite, the color separator cannot accurately separate the wollastonite. Only the artificial intelligence ore separator can establish the separation model based on the multi-dimensional characteristics of good and bad materials in the raw ore, and achieve the final separation accuracy and bring out the good and bad materials with low yield through the artificial intelligence technology. Project advantages In the application of artificial intelligence in wollastonite, it can completely replace manual selection. If the wollastonite is well dissociated, the artificial intelligence machine can directly separate the wollastonite and tailings, which has the advantages of high efficiency, good effect and low cost. The cost is mainly the one-time equipment procurement cost and the subsequent equipment power supply cost. If the degree of dissociation is general, the ore with good wollastonite grade can also be separated by the artificial intelligence machine, or the useless waste rock can be discarded, which can directly reduce the amount of ore entering the magnetic separation or flotation, save the cost of magnetic separation and flotation, and reduce the treatment level of tailings. In particular, Mingde Optoelectronics artificial intelligent sorter has been widely used in various ore sorting fields at this stage, not only in wollastonite, but also in ores with visible differences, both in the scope of artificial intelligent sorter. The equipment has withstood the test of various industrial and mining enterprises in terms of technical maturity and practical application effect.

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.  

Coal gangue as a coal mining process produced in the largest number of industrial solid waste, improper handling will cause some damage to the environment and pollution, and in the process of dealing with coal gangue because of its large processing level, low economic benefits, is a more headache for coal mining enterprises. According to the statistics of the relevant departments, the current coal gangue stockpile amounted to more than 3 billion tons, of which the coal system in order to discharge nearly 100 million tons of coal gangue growth each year. Different across the country because of coal storage and production, there are big differences in the coal gangue treatment process policy, to the coal province of Shanxi, for example, coal enterprises mining process generated by the coal gangue, because of its great amount, as construction materials, road construction, etc. The supply far exceeds the demand, resulting in coal enterprises coal gangue treatment is still a huge problem. Among them, coal gangue as coal mining, washing and other aspects of solid waste, in which there are also associated minerals with economic mining grade, mainly because of its sorting difficulty, sorting costs and other factors. The vast majority of them are still treated in a simple and crude way, resulting in low socio-economic benefits of coal gangue. In order to respond to such needs, we Mingde Optoelectronics launched an X-ray artificial intelligence sorting machine. X-ray intelligent sorting machine, can be pre-precision throwing waste - advance sorting of high-grade gangue associated ore, to achieve economic mining grade, directly increase enterprise revenue, significantly reduce the amount of gangue into the "research - grinding - crushing The amount of gangue into the "research-grinding-crushing" process, effectively throw away the waste rock in the gangue, reduce the amount of gangue processing and processing costs, indirectly improve the comprehensive benefits of the original mine, but also reduce the pollution of the environment and the generation of tailings, to achieve the maximum use of resources, waste into treasure, but also in line with the national green mine development direction.   Hefei Mingde Optoelectronics Technology Co.   Founded in 2014, is a national high-tech enterprise specialized in visible light, intelligent sorting technology and X-ray overall solution for industrial and mining industry. We have a high-quality R & D, production team, with mature artificial intelligence, X-ray product development experience, access to all kinds of core patents more than 80.   Self-developed artificial intelligence ore sorter and X-ray intelligent sorter have achieved industrial field production applications for various mineral species, of which artificial intelligence ore sorter is now widely used in talc, magnesite, wollastonite, industrial silicon, gold ore, fluorite, lithium ore and other industrial and mining enterprises.   X-ray intelligent sorting machine applications include non-ferrous metal ore (lead, zinc, copper, molybdenum, nickel, gold, silver, tin, etc.), ferrous metal ore (manganese, iron, chromium, vanadium, titanium, tungsten), non-metallic ore (phosphorus, fluorite, magnesite, coal gangue, etc.), other solid waste, smelting waste ore. Our service customers cover all kinds of large, medium and small ore enterprises at home and abroad. Mingde Optoelectronics is the only company in China that has mature applications in non-ferrous metal ore, ferrous metal ore, non-metallic ore, coal mine, as well as recycling resources and waste sorting. Mingde photoelectric X-ray intelligent sorting machine is different from traditional mineral processing equipment, using X-ray transmission ore, according to different material attenuation specificity, identify the internal structure of the ore, the use of AI artificial intelligence means, customized sorting of ore, can be self-learning, highly intelligent.

Potassium feldspar is also known as orthoclase, the color is usually red flesh red, yellowish white, in addition to orthoclase there are also perovskite and triclinic crystal system. Usually density in 2.54-2.57g/cm³, abrasive materials and other industrial sectors and the production of potash fertilizer with. Among them in the ceramic industry as embryo ingredients, glaze dosage accounted for 30%, the rest are mostly used in chemical, glass, glass fiber and other industries, with the development of China's social and economic development, the increasing demand, potassium feldspar application prospects are more promising. The main problem of domestic potassium feldspar at this stage, rich in resources, potassium feldspar is mostly symbiotic with quartz, but also with iron-bearing minerals, mica, clay minerals and rutile. In order to improve the industrial value of potassium feldspar, its beneficiation and removal of miscellaneous stones is essential, especially the domestic potassium feldspar contains excessive iron, iron removal is the key to purification.        Next, a brief description of how to remove potassium feldspar and beneficiation equipment process flow. Photoelectric Separation and Removal      Potassium feldspar photoelectric sorting and debris removal, mainly is the original potassium feldspar ore after coarse break or second break associated ore can be sorted and dissociated, the use of photoelectric sorting equipment pre-throw waste tailings, remove the potassium feldspar in the useless quartz, vein or can be separated from the material, so as to achieve the purpose of separation, compared with the traditional hand sorting process, the overall sorting efficiency is greatly improved. Magnetic Separation     Since iron minerals, black mica, tourmaline, etc. in potassium feldspar are weakly magnetic, they can be removed by strong magnetic separation process and equipment to achieve the purpose of separation. Removal of impurities by flotation     When potassium feldspar contains pyrite, mica, or garnet, tourmaline, hornblende and other forms of ferrite containing minerals, the flotation process is mostly used to remove impurities. The process flow of mineral potassium feldspar beneficiation equipment is as follows.    Crushing: Firstly, the raw ore is crushed by jaw crusher, and then sent by belt conveyor to cone crusher for secondary crushing;   Sorting: After the secondary crushing, the potassium feldspar particles are sent to the circular vibrating screen for sieving and transported to the ore color sorter or artificial intelligence ore sorter for sorting, and the waste stone is thrown away after crushing and dissociation;    Ball Mill: After the waste throwing, the concentrates enter the ball mill for ball milling, and the potassium feldspar powder after ball milling is sorted by spiral classifier;     Magnetic separation: The finely ground potassium feldspar powder enters the magnetic separator for magnetic separation, and the selected iron and mica materials are sorted out by strong magnetism according to the material condition.    Flotation: potassium feldspar through flotation, can be very good to enhance the effect, not only to remove iron, titanium, but also to separate out the quartz and other substances. Among them, according to the potassium feldspar companion does not understand, the use of pharmaceuticals will be different, the main agents are acid flotation, neutral flotation, alkaline flotation method. Dewatering and drying: Potassium feldspar concentrate after magnetic separation or flotation or composite sorting. Dehydration treatment by thickener, then into the dryer for rapid dewatering and drying, and finally the dried potassium feldspar powder is the final sorted potassium feldspar concentrate. Among them, the above process flow 4 and 5 because of the different iron content in potassium feldspar and the different forms of iron ore present in it, sometimes magnetic separation or flotation can be used for sorting, but some potassium feldspar iron ore content is high, and sometimes iron ore exists in potassium feldspar in the form of leaching, this kind of belongs to the difficult ore species, at this time will use the joint beneficiation process for sorting, such as magnetic separation - flotation method, reverse flotation - strong magnetic separation method, etc., at this time can be used Joint beneficiation process, such as magnetic separation - flotation method, reverse flotation - strong magnetic separation method, etc.   From the potassium feldspar beneficiation process, the equipment to be used are jaw crusher, cone crusher, ball mill, vibrating feeder, spiral classifier, ore color separator, artificial intelligence sorter, magnetic separator, flotation machine, dryer, vibrating screen, conveyor, etc. According to the existence of different forms of potassium feldspar, there will be some differences in equipment.    The above is the potassium feldspar sorting process, equipment and process flow, Anhui MINGDER is mainly specialized in ore sorting equipment research and development, production, sales in one of the photoelectric sorting high-tech enterprises, the main products are ore color sorting machine, artificial intelligence sorting machine, mineral sand sorting machine, X-ray intelligent sorting machine, not only use potassium feldspar sorting, in all kinds of metal non-metallic ore are used, covering fluorite, talc, silica The scope of coverage includes fluorite, talc, silica, quartzite, phosphate ore, gold ore, high crystalline silicon, coal and coal gangue, etc.      

Phosphate ore is a general term for phosphate minerals that can be used as an important chemical material, mainly used in medicine, food, matches, dyes, sugar, ceramics, national defense and other industrial sectors, as well as an important mineral raw material for the extraction of phosphate fertilizer.   China's phosphate ore reserves are currently ranked third after Morocco and the United States, domestic phosphate ore distribution is concentrated in Yunnan, Guizhou, Sichuan, Hubei and Hunan 5 provinces, the total reserves account for about 74.5% of the country, phosphate ore by the formation of two main types of apatite and phosphorite, where apatite is mainly in igneous or metamorphic rocks in the form of crystalline apatite, phosphorite is gray-black, cryptocrystalline microcrystalline structure, breccia structure. Now known to contain phosphorus minerals in more than 120 kinds, now the industrial use of phosphate ore is mainly apatite, in fact, for sulfur phosphorus aluminum strontium stone, blue iron stone, etc., of which more than 95% of the phosphorus element mainly several species in the apatite.  There are more associated minerals in natural phosphate ore, mainly miscellaneous rocks and veins, specifically two types of silica minerals and carbonates. Silica minerals are mainly quartz, quartz square, flint, opal, clay ore or other silicate minerals such as feldspar, mica, etc. Carbonates are mainly limestone and dolomite.      The goal of phosphate ore enrichment is to maximize the separation and removal of impurity minerals and improve the grade and quality of phosphate ore. The enrichment process includes crushing and separation (crushing and crushing), washing and classification (washing and classification), separation and purification (flotation, magnetic separation, photoelectric separation, calcination, heavy media separation), the three main steps. The process and operation of phosphate ore preconcentration and discarding are as follows. 1. Crushing and separation      Phosphate ore enrichment requires crushing and smashing to achieve monomeric dissociation of phosphate minerals and veinlets, mainly because the phosphate minerals and miscellaneous stones are in cementation together, the original ore can only be broken and ground to achieve monomeric dissociation. This step is the basic step of phosphate ore enrichment. 2. Water washing classification     Phosphate ore due to the mining process in the wet ore adhering to the mud, only after water washing to remove the mud, while water washing can also remove soluble water substances and so on. Because the phosphate ore after crushing, water washing particle size is different, you need to go through the classification equipment to sort out the appropriate particle size. Only then can further enrichment and purification. 3. Separation and purification      After the above process, phosphate ore into the final separation and purification steps, phosphate ore purification are mainly heavy media separation, photoelectric separation, calcination, flotation, magnetic separation. 1) Flotation     Flotation mainly has positive and negative flotation, mainly using phosphate ore and miscellaneous ore physical properties are different, the use of flotation agents to make phosphate ore float or sink, so as to achieve the purpose of separation. 2) Magnetic separation      The use of iron-containing magnetic minerals in phosphate ore, under the action of magnetic separator, and non-magnetic vein recovery of phosphate ore containing iron magnetic minerals separation. 3)Calcination     Mainly used to remove organic matter, carbon dioxide and part of the fluorine in the phosphate ore, calcination temperature of 400 ~ 1400 ℃, depending on the purpose. 4)Photoelectric sorting     Mainly phosphate ore after crushing, the use of ore surface characteristics differences, through the color sorter or artificial intelligence sorter for sorting. 5)Heavy media sorting    Using the difference in density between phosphate ore and other minerals, a medium is selected so that one medium floats and the other sinks, thus achieving enrichment.      The above is the way of phosphate ore sorting and purification applications, where the mainstream sorting is mainly using heavy media sorting and photoelectric sorting (X-ray sorting), a small number of flotation, magnetic, calcination process. Next, we will elaborate on the mainstream phosphate ore separation and purification process. First of all, heavy media sorting is the use of phosphate ore, dolomite, shale specific gravity differences to sort, where phosphate ore, dolomite, shale density distribution of 2.2g/cm³, 2.8-2.9g/cm³, 2.55 ~ 2.65g/cm³, in the actual sorting process, subject to the influence of a number of factors, phosphate enrichment has nearly 8% or so dolomite carry out, greatly affecting the phosphate enrichment after the quality.       At the same time, there are some phosphate mining enterprises have used X-ray equipment for sorting, X-ray equipment sorting is similar to heavy media sorting, mainly using the density difference between mineralized and non-mineralized materials for sorting, in the field production process, because the phosphate ore and associated ore density difference value is small, imaging is closer, there will be throwing waste tailings phosphate ore with high, the actual application of phosphate ore is not particularly ideal. The current stage of the situation and problems faced by phosphate ore sorting, the introduction of artificial intelligence sorting machine, the main principle is the use of phosphate ore surface characteristics of the differences in sorting, to accurately identify the phosphate ore and dolomite and shale surface texture, luster, color, shape and other characteristics of the subtle differences, a composite sorting, sorting effect is higher than the current stage of phosphate ore enrichment accuracy and effectiveness.       Mingde photoelectric recently used artificial intelligence ore sorting machine,digital color separating machine, sorting phosphate ore original grade of about 20, after enrichment of the concentrate grade of about 30, tailings in the phosphate ore grade is less than 5. fully able to meet the target sorting requirements. At the same time, it can guarantee the amount of bad material to be taken out under the premise of enriching the phosphate ore grade, and also take into account the rate of good material to be taken out from the waste tailings.   Here is the phosphate ore after sorting Mingde photoelectric focus on the field of ore sorting, after a long period of technical accumulation and ore field of sorting applications, the introduction of four series of more than 20 products, widely used in fluorite, talc, wollastonite, high crystal silicon, iron ore, gold ore, lead and zinc ore, coal and coal gangue, vanadium ore and nearly 100 kinds of metal, non-metallic ore field of sorting applications.     Edit by Jacky

Beneficiation process and technology of various iron ores Iron sore sorting technology Mineral processing technology and mineral processing equipment are developed at the same time. The technical level of equipment not only reflects the mineral processing technology, but also directly affects the production process, effect, efficiency and economic benefits of industrial ore dressing. Industrial ore dressing process mainly includes crushing, screening, grinding (ball mill), classification (classifier), separation (gravity separation, flotation, magnetic separation, photoelectric separation), mineral dehydration (concentration, filtration, drying, etc.). The final purpose of beneficiation is mainly to separate minerals from gangue, so as to achieve monomer separation and make final preparation for separation operation. Beneficiation equipment mainly includes crusher, feeder, ball mill, classifier, vibrator, shaker, magnetic separator, mixing bucket, flotation machine, artificial intelligence separator and other equipment. There are many kinds of iron ores, which can be mainly divided into strong magnetic iron ores and weak magnetic iron ores, among which strong magnetic iron ores include magnetite, titanomagnetite and pyrrhotite; Weak magnetic iron ores include hematite, pseudohematite, limonite, siderite and ilmenite. According to the characteristics of different iron ores, there will be different beneficiation processes. The following are mainly the beneficiation processes and emerging beneficiation technologies applied to different iron ores picture 1. Beneficiation of strong magnetic ore Strong magnetite is mainly divided into two types of single type and polymetallic type magnetite. ① Single type magnetite beneficiation The mineral substance of single type magnetite ore is mainly magnetite. Due to its simple composition, weak magnetic separation is usually used for beneficiation. According to the limit of magnetite grinding particle size of 0.2mm, one-stage grinding magnetic separation is adopted when the size is larger than 0.2mm; If it is less than 0.2mm, two-stage grinding magnetic separation is adopted. If the qualified tailings can be separated in the coarse grinding stage, the separation grinding magnetic separation is adopted. For some water shortage areas, dry grinding and dry magnetic separation are adopted. At the same time, in order to obtain high grade iron ore concentrate, concentrate can be enriched by flotation, shock fine screen, etc. ② Beneficiation of polymetallic magnetite The processing of polymetallic magnetite is mainly composed of silicate or carbonate minerals, and associated with cobalt pyrite, chalcopyrite and apatite, the weak magnetic separation reverse flotation process can be used, that is, the weak magnetic separation process is used to recover iron, and then the flotation process is used to recover sulfide or apatite. According to the different reagent systems, especially the types of collectors, the weak magnetic separation reverse flotation process can be divided into weak magnetic separation cation reverse flotation process and weak magnetic separation anion reverse flotation process. picture 2. Beneficiation of weak magnetic ore Weak magnetite is also divided into two types of single type and polymetallic weak magnetite. ① Beneficiation of single weak magnetic iron ore Single weakly magnetic iron ores mainly include hematite, siderite, limonite and hematite (specularite) - siderite, etc. Because this kind of mineral involves many kinds and has a wide range of embedded particle sizes, the beneficiation method is also complex, and gravity separation, flotation, high intensity magnetic separation or their combined processes are often used. At the same time, photoelectric separation can also be used to enrich the iron ore grade before the existing beneficiation process. The flotation process is used to separate fine and fine weakly magnetic iron ores, mainly including positive flotation and reverse flotation. Among them, the positive flotation process is applicable to quartz hematite ore without easy floatation gangue, while the reverse flotation process is applicable to gangue easy floatation ore. Gravity separation and high intensity magnetic separation are mainly used for 2-20mm and medium weak magnetite, and heavy medium or jigging beneficiation of ore larger than 20mm, or artificial intelligence machine can be used for beneficiation. The photoelectric separation process is applicable to ores with particle size of 0.5-10cm. Through artificial intelligent separation equipment, waste gangue is pre discarded, iron ore is enriched, grinding and iron ore flotation are reduced, and the overall economic benefits of the mine are improved. ② Beneficiation of polymetallic weakly magnetic iron ores They are mainly hydrothermal and sedimentary hematite ore or siderite ore containing phosphorus or sulfide. Such ores are generally recovered from iron minerals by photoelectric separation, gravity separation, flotation, strong magnetic separation or their combined processes, and phosphorus or sulfide by flotation. Hydrothermal apatite bearing hematite ore and copper bearing pyrite can be flotation. Sedimentary phosphorus containing oolitic hematite ore can be separated from iron by flotation, but it is often difficult to enrich phosphorus concentrate, and the iron recovery rate is greatly reduced. It can be considered to smelt high phosphorus pig iron and recover steel slag phosphate fertilizer after removing large grain gangue by artificial intelligence sorting equipment. The above are common ore dressing methods. The above methods can be used for reference when processing iron ore beneficiation. However, in actual beneficiation, it is necessary to go through beneficiation tests to determine the ore composition and ore properties, and then, according to the analysis results, actual conditions and investment conditions, customize a reasonable process flow that meets its own mine conditions. At the present stage, mine beneficiation mainly applies gravity separation, magnetic separation, flotation or combined process. However, in the development of beneficiation processes at home and abroad, the fourth beneficiation process - photoelectric separation has also undergone nearly 20 years of development, from the initial color separation era to artificial intelligence separation. Among them, the representative brand "Mingde Optoelectronics" has been specialized in ore beneficiation since its inception, The representative products of photoelectric separation include ore color separator, mineral sand separator, artificial intelligent separator and X-ray intelligent separator. In the field of iron ore separation, in order to solve the problem of ore dressing difficulties, improve the comprehensive utilization rate of mine resources, drive the overall economic benefits and other advantages, it has accumulated mature experience, and has been applied to various metal and non-metallic ore dressing fields.  

Non ferrous metals refer to all metals except iron and iron base alloys, chromium and manganese. They are also divided into five categories: nonferrous heavy metals, nonferrous light metals, rare metals, precious metals and semi metals. Common nonferrous metals include copper, lead, zinc, aluminum, vanadium, tungsten, lithium, gold, silver, silicon, rare earth, etc. Non ferrous metals are basic materials for national economic development, such as aerospace, automobile, machinery manufacturing, power, communications, construction Most industries such as household appliances are based on nonferrous metal materials.   The distribution of nonferrous metals in China is more in the south than in the north, mainly in the Yangtze River basin. The ore deposits are mostly divided into blocks and belts in spatial distribution. Non ferrous metals are formed in the process of magma cooling, and there are many ways such as gravity, replacement, recrystallization, and sublimation. Most of them occur in fault fracture zones, magmatic rocks, or contact inner and outer zones, fold cores. In terms of mineralization, magmatic rocks are important factors for nonferrous metal mineralization. Nonferrous metal beneficiation is based on the difference of physical and chemical properties of different ores. After crushing and grinding of raw ores, mineral processing technology is used to separate minerals from gangue to remove or reduce harmful impurities. Metal products are produced after smelting. Domestic beneficiation processes mainly include gravity separation, magnetic separation, flotation and electric separation, such as gravity separation of copper, lead, zinc, etc; Magnetic separation of sulfide ores; Flotation of gold, silver, copper, lead, zinc, molybdenum, etc; Separation of scheelite and cassiterite by electric separation, and selection of tantalum niobium ore. The nonferrous metal ores are mostly multi metal symbiosis, and the nonferrous metal grades in ores are generally low. Only when certain reserves and the lowest industrial mining grade are reached, can they have the value of mining and beneficiation. Generally, smelting a ton of nonferrous metals often requires mining hundreds to tens of thousands of tons of ores. In the beneficiation process, most raw ores are directly crushed and grinded without pre throwing waste tailings, resulting in large ore handling capacity, limited production capacity, high energy consumption, high cost, large tailings handling capacity, and large environmental impact of the gravity and magnetic levitation electric separation process, reducing the economic benefits of the mine. However, AI separation can make use of the difference in ore surface characteristics and imaging differences to directly pre dispose the waste tailings, enrich the grinding ore grade, reduce the cost of grinding, beneficiation electricity, reagents, etc. In terms of reducing energy consumption, improving production, increasing benefits, and building smart and green mines in mine beneficiation, AI separation has a wide application space and value for industrial and mining enterprises to enrich and pre dispose the waste. Conventional beneficiation process and flow of non-ferrous metals The vast majority of non-ferrous metals are beneficiated by flotation method, a small part by magnetic separation and gravity separation, and some by chemical or electric separation. The existing mineral processing processes are all based on the physical or chemical characteristics of minerals to dissociate, so as to achieve the purpose of selecting qualified concentrates.   In the flotation method, the raw ore is broken and grinded to fully separate the minerals. With the help of reagents, the useful minerals are attached to the bubbles and the useless minerals are left in the pulp to achieve the purpose of separation. The conventional process of "one roughing, two sweeping and three cleaning" is adopted for flotation separation. Such as chalcopyrite, galena, spodumene, etc. The magnetic separation method uses the magnetic principle of minerals and relies on magnetic fields to distinguish the minerals with strong magnetism, medium magnetism and weak magnetism. For example, chalcopyrite and wolframite are separated from gangue by magnetic separation. By gravity separation, some non-ferrous metals have large density, and the specific gravity of minerals and gangue varies greatly. When mineral particles with different specific gravity move in the same medium, they are loosened by gravity, medium resistance, etc., so as to achieve the goal of mineral separation. Such as wolframite, zircon, cassiterite, etc. The electric separation method mainly uses the different conductivity of minerals and gangue to separate minerals through high voltage electric field. Such as the separation of scheelite and cassiterite, and the separation of tantalum niobium ore and garnet. In chemical method, there are chemical differences between minerals and components. Solid metal minerals are dissolved into liquid through acid, ammonia and other leachants, such as copper ore in malachite. Copper sulfate solution is obtained by soaking in dilute sulfuric acid. Enriched copper can be obtained by replacing copper ions with iron ions. In a word, most nonferrous metals have low grade in nature as a whole. Only through crushing grinding floating magnetic gravity electrochemical method can minerals be enriched. However, the tailings waste a lot of electricity and reagents due to the above processes, resulting in high selection costs. Artificial intelligence and X-ray intelligent sorting system Mingde artificial intelligent sorter and X-ray intelligent sorter are two series of products developed with great concentration through technical accumulation and advantages, combined with the difficult problems of separation and beneficiation in industrial and mining enterprises. It is applicable to most nonferrous metals, ferrous metals, nonmetals, and others such as coal gangue and solid wastes. It can discard tailings, enrich ore grade, reduce grinding and dressing costs, and increase economic benefits of industrial and mining enterprises.   In the flotation method, the raw ore is broken and grinded to fully separate the minerals. With the help of reagents, the useful minerals are attached to the bubbles and the useless minerals are left in the pulp to achieve the purpose of separation. The conventional process of "one roughing, two sweeping and three cleaning" is adopted for flotation separation. Such as chalcopyrite, galena, spodumene, etc. The magnetic separation method uses the magnetic principle of minerals and relies on magnetic fields to distinguish the minerals with strong magnetism, medium magnetism and weak magnetism. For example, chalcopyrite and wolframite are separated from gangue by magnetic separation. By gravity separation, some non-ferrous metals have large density, and the specific gravity of minerals and gangue varies greatly. When mineral particles with different specific gravity move in the same medium, they are loosened by gravity, medium resistance, etc., so as to achieve the goal of mineral separation. Such as wolframite, zircon, cassiterite, etc. The electric separation method mainly uses the different conductivity of minerals and gangue to separate minerals through high voltage electric field. Such as the separation of scheelite and cassiterite, and the separation of tantalum niobium ore and garnet. In chemical method, there are chemical differences between minerals and components. Solid metal minerals are dissolved into liquid through acid, ammonia and other leachants, such as copper ore in malachite. Copper sulfate solution is obtained by soaking in dilute sulfuric acid. Enriched copper can be obtained by replacing copper ions with iron ions. In a word, most nonferrous metals have low grade in nature as a whole. Only through crushing grinding floating magnetic gravity electrochemical method can minerals be enriched. However, the tailings waste a lot of electricity and reagents due to the above processes, resulting in high selection costs. Artificial intelligence and X-ray intelligent sorting system Mingde artificial intelligent sorter and X-ray intelligent sorter are two series of products developed with great concentration through technical accumulation and advantages, combined with the difficult problems of separation and beneficiation in industrial and mining enterprises. It is applicable to most nonferrous metals, ferrous metals, nonmetals, and others such as coal gangue and solid wastes. It can discard tailings, enrich ore grade, reduce grinding and dressing costs, and increase economic benefits of industrial and mining enterprises.

Mingde Artificial Intelligence Mineral Separator Do Favour to Fluorite Sorting Fluorite, also known as fluorspar, the main component of calcium fluoride, is more widely used, such as in the steel industry as a flux, in porcelain enamel to help color and flux, in the field of optics for lenses, acid grade fluorite concentrate can be used to produce hydrofluoric acid, is almost so the main source of elemental fluorine.    China as the world's largest producer and consumer of fluorspar, China's fluorspar ore reserves in the world's first, fluorspar ore reserves are relatively concentrated, of which Zhejiang, Hunan, Inner Mongolia accounted for about 72% of domestic reserves, these reserves have relatively concentrated in several large deposits, domestic fluorspar ore characteristics are: monotypic fluorspar deposits, less reserves, more poor ore, less rich ore, and fluorspar associated ore, large reserves, more difficult to select ore, easy beneficiation ore less. The value of fluorite ore utilization is greatly restricted.      At this stage, the domestic fluorite ore beneficiation methods are mainly the following, hand-selected, gravity (jigger) selection and flotation beneficiation. Among them, hand sorting is mainly on the fluorite and vein boundaries, easy to sort fluorite applicable, gravity separation is mainly selected for higher taste, particle size in 6-20mm fluorite ore, flotation is mainly to separate fluorite in the quartz, barite, calcite and other vein minerals, need to be ground to -200 mesh below the sorting.         All of the above types of sorting are very limited restrictions, hand-selection efficiency is low, high personnel costs; gravity separation grade requirements, high requirements for the original fluorite can be selected; flotation costs are high, the environmental damage. In the process, cost, resource utilization, economic efficiency and other aspects in urgent need of upgrading.         Then we have to mention today to talk about an emerging ore sorting equipment - artificial intelligence ore sorting machine, perfectly compatible with the process content of hand + gravity separation, while reducing the amount of flotation ore through sorting, but also to solve the problem of color sorting machine sorting fluorite precision is not high.         The main application area of artificial intelligence ore sorting machine is industrial and mining enterprises, mainly using visible light for sorting, using a mature artificial intelligence means, able to sort according to the eye to see various differences in the ore, such as color, shape, texture, texture, reflectivity and other characteristics, sorting is a composite once sorting, combined with a variety of features to establish the model, in the artificial intelligence to sort out the good material and tail material, and Solve the limitations of color sorting machine can only be based on a single color to discriminate. Especially in fluorite ore, because of its different colors and different crystal shapes, such as octahedral, cubic, granular, grape, spherical and other characteristics of great differences, and the difficulty of sorting, the application of artificial intelligence machine is promising.   Fluorite sorting case       First of all, artificial intelligence ore sorting machine compared to hand sorting, has the advantages of strong stability and large sorting scale; compared to gravity separation, high grade fluorite low grade fluorite, particle size in 0.3-10cm can be sorted, breaking the limitations of gravity separation; compared to flotation, fluorite in crushing and dissociation can be directly into the artificial intelligence ore sorting machine, fluorite ore pre-throw waste, sorting out fluorite concentrate and throw waste in the original ore The fluorite concentrate can be sold directly and the waste stone can be backfilled or sold as construction material; for the fluorite ore which is not easy to dissociate, we can sort out the high grade for enrichment and throw away the waste directly for the lower economic grade, which reduces the amount of ore for flotation and saves the cost of flotation, and at the same time reduces the amount and cost of handling the tailings after flotation.         Mingde photoelectric artificial intelligence ore sorting machine face industrial and mining enterprises, can adapt to the requirements of high dust, high pollution, high corrosion and other harsh environment. At the same time to enhance the comprehensive utilization and economic value of fluorite ore, reduce the mining grade requirements, Mingde photoelectric for the solution of industrial and mining enterprises sorting problems, has been helping to move forward.

Photoelectric separation technology contributes to the risk management of tailings At the beginning of November, the State Administration of Mine Safety issued a notice on the overall plan for the management of hidden risks in tailings reservoirs, in view of the risk hidden trouble treatment of the tailing pond, the paper puts forward the principle of organizing and implementing the measures according to local conditions, comprehensive measures, giving prominence to the key points and implementing them step by step, closing the pond and canceling the number, eliminating the risks, carrying out the responsibility, strengthening the management, considering as a whole and advancing comprehensively, according to the level of risk, carry out risk management of the tailing pond in batches and years, and strive to reach the 2026 level, about 200"Overhead depots", 700 depots with no main body of production and operation, and long-term defunct and high-risk hidden danger tailings depots have been completed nationwide. According to incomplete statistics, at present our country tailings and waste rock pile stock situation, non-metal mines (except coal mining) every year about 1 billion tons of waste rock, accumulated more than 10 billion tons;  Every year, about 3 billion tons of waste rock are added to the metal mines, and the accumulative stock of industrial solid waste such as waste rock and tailings has reached more than 70 billion tons, and is increasing continuously. If the solid waste from mines can not be discharged and stored scientifically, it will destroy woodland, occupy land, pollute water and environment, and even cause serious safety accidents. At present, in view of tailings and waste rock, the generation and utilization of tailings and waste rock can be reduced as much as possible in the production link by means of open source and throttling, existing tailings and waste rock through how from can be used to achieve utilization. Utilization of tailings It is mainly to enhance the recovery of high-value components in the tailings, and to enhance the economic benefits of the tailings. 1) the tailings are separated by photoelectric separation equipment. On the premise of increasing the comprehensive utilization ratio of the tailings greatly, the tailings are enriched for metal ores to reach the economic mining grade. The non-metallic ores are separated by equipment, and the waste rock is pre-cast to separate the non-metallic ores which have economic value. (2) to strengthen the vegetation coverage and management of the mine land, and to reduce the environmental damage and impact by means of reclamation and Afforestation. The use of waste rock 1) in the waste rock, there are also some metal ores with high value, which have high recycling value, and the grade is often higher than the corresponding primary ore grade, such as gold enrichment and recovery by means of chemical mixed flotation, sulfide concentrate grinding, cyanide leaching, photoelectric separation, etc. . 2) it can backfill the mine through waste rock and use it as mine filling material. In a word, in view of the treatment of tailing pond and the production of tailing, the Economic Benefit is the guide, and the introduction and use of new technology is the guidance. It can reduce the difficulty and cost of tailings reservoir treatment, enhance the comprehensive utilization value of the mine, reduce the long-term impact on the environment, and save a lot of tailings treatment cost. X-ray intelligent sorting machine Hefei Mingde opto-electronic technology co. , Ltd. is a national high-tech enterprise dedicated to intelligent sorting technology and X-ray integrated solutions. The company has always focused on the field of ore separation, research and production of ore color separators, artificial intelligence separators, x-ray intelligent separators, can be applied to nearly 100 kinds of metal, non-metallic ore separation applications. Its photoelectric separation technology is not only the innovation of mineral processing technology, but also has a far-reaching influence on the whole industry and mining link, such as mine, mine, tailing pond and so on. Value and advantages of photoelectric sorting Through physical separation, using the difference of ore surface characteristics or internal density difference for separation. Compared with the traditional flotation, grinding and separation of tailings into a slurry-like, difficult to deal with, deep environmental damage, photoelectric separation of materials specifications of 0.3 cm or more, the waste tailings after separation can be directly used as backfill and building materials, which reduces the difficulty of tailings treatment, improves the economic value of the mine and indirectly prolongs the service life of the mine. At the same time in line with the policy trend of mining, greatly reducing the production of tailings.
