Ore photoelectric sorting is an advanced mineral sorting technology. It uses photoelectric sensors to detect and identify minerals based on the photoelectric properties of minerals to achieve effective mineral sorting. This technology imitates the action of hand selection, and greatly improves the efficiency and accuracy of mineral processing through a combination of machinery and electricity. During the ore photoelectric sorting process, the photoelectric sensor emits a beam of light to the mineral. Minerals absorb the energy of light and reflect it. Different types of minerals have different spectral characteristics of absorption and reflection due to differences in their internal structures and compositions. Photoelectric sensors can accurately identify minerals by capturing these reflection spectral features. Ore photoelectric separation technology is widely used in the separation process of various ores, especially in the primary selection of pegmatite quartz vein-type ores. It can partially replace the traditional manual selection method, reduce labor intensity and improve production efficiency. In addition, ore photoelectric separation technology is also widely used in scenarios such as pre-disposal waste treatment, low-grade ore enrichment, and sorting of associated ores of multiple mineral types. Pre-disposing waste treatment is one of the important applications of ore photoelectric separation technology. In the process of ore mining and processing, there are often large amounts of gangue and low-grade ore. Through photoelectric separation technology, these useless or low-value minerals can be effectively separated, thereby reducing the amount of waste rock in subsequent treatment processes and reducing the overall cost of mineral processing. Low-grade ore enrichment is another important application area. Many ores cannot meet the requirements of economic mining due to their low grade. Through ore photoelectric separation technology, the useful components in these low-grade ores can be effectively enriched and the grade of the ores can be improved, making them economically valuable for mining. Low-grade ore enrichment is another important application area. Many ores cannot meet the requirements of economic mining due to their low grade. Through ore photoelectric separation technology, the useful components in these low-grade ores can be effectively enriched and the grade of the ores can be improved, making them economically valuable for mining. The sorting of multi-mineral associated ores is also an important application scenario of ore photoelectric separation technology. In ores associated with multiple mineral types, the property differences between different minerals may increase the difficulty of mineral processing. Through photoelectric separation technology, different minerals can be effectively separated, reducing the difficulty of mineral processing and improving the efficiency of mineral processing.

1. Which links in the mineral processing process are likely to affect efficiency? In the mineral processing technology, multiple links may affect the mineral processing efficiency, and the following links are more likely to have a significant impact on the mineral processing efficiency: (1) Pre-election preparation stage: Crushing and Screening: Ore crushing and screening are key steps before mineral processing, which directly affect the efficiency and effect of subsequent mineral processing. In the crushing operation, if the crusher is improperly selected or operated, it may lead to insufficient or excessive crushing of the ore, affecting the efficiency of subsequent grinding and mineral processing. Screening is used to classify the crushed ore according to particle size to provide suitable raw materials for the processing. Grinding and Classification: Grinding is the continuation of the ore crushing process, and its purpose is to separate various useful mineral particles in the ore into monomers for selection. The selection of grinding mills and the control of the grinding process are crucial to the efficiency of mineral processing. The classification operation affects the classification particle size and processing capacity by adjusting parameters such as the size of the classification area, the height of the overflow weir and the speed of the spiral, thereby affecting the efficiency of mineral processing. Selection stage: The properties of the ore, the selection of the beneficiation equipment and the selection of the beneficiation method will affect the efficiency of the beneficiation stage. For example, the particle size of the mineral has an important influence on the flotation efficiency. Too fine a particle size will deteriorate the flotation effect. The selection of the flotation machine speed will also affect the stirring intensity of the slurry and the flotation effect. Dehydration stage after selection: The concentrate obtained by wet beneficiation usually contains a lot of water. The efficiency of the dehydration stage directly affects the quality and output of the concentrate. The dehydration stage includes processes such as concentration, filtration and drying. The effects of these processes are affected by factors such as equipment performance, operation level and the properties of the original ore. Slurry concentration: Appropriate pulp concentration has an important impact on flotation efficiency. Within a certain range, increasing pulp concentration is conducive to the collision and contact between minerals and reagents, thereby improving flotation efficiency. However, excessive pulp concentration will increase reagent consumption, deteriorate aeration effect, and reduce flotation efficiency. Operation and management: The skill level and management level of operators also have an important impact on mineral processing efficiency. Modern and digital management methods can optimize the mineral processing process and improve production efficiency. At the same time, strengthening the management and awareness of mining companies and avoiding management and awareness deviations are also important measures to improve mineral processing efficiency. To sum up, many links in the mineral processing process may affect the efficiency, but factors such as the preparation stage before mineral processing, the separation stage, the dehydration stage after mineral processing, as well as slurry concentration and operation management have the most significant impact on mineral processing efficiency. By optimizing these links and factors, the mineral processing efficiency can be significantly improved, production costs can be reduced, and the sustainable development of the mine can be achieved. 2. In order to optimize the links that affect efficiency in the mineral processing process, we can consider and implement them from the following aspects: (1) Grinding and grading operations: Optimize grinding process parameters: According to the characteristics of the ore, study the grinding index and formulate appropriate grinding process parameters. For the ore dressing plant with "over-grinding" phenomenon, selective grinding technology can be considered. Use efficient grading equipment: Although spiral classifiers are commonly used, their grading efficiency is generally only 20% to 40%. Consider introducing efficient grading equipment such as hydrocyclones or high-frequency vibrating fine screens to improve grading efficiency. However, attention should be paid to the stability of hydrocyclones. (2) Selection of work: Select or improve mineral processing equipment: In flotation operations, the selection of flotation machines is crucial. According to the characteristics of the ore and the flotation process, select or design a suitable flotation machine. At the same time, pay attention to the development of flotation reagents and processes, and adopt the latest flotation technology and reagents. Optimize flotation conditions: According to the properties of the ore, adjust the parameters such as pulp concentration, stirring intensity, and aeration volume during the flotation process to obtain the best flotation effect. (3) Dehydration operation: Introduce advanced dehydration equipment: such as disc vacuum filter, which not only has large processing capacity and good dehydration effect, but also has low energy consumption. Optimize the dehydration process: By adjusting various links in the dehydration process, such as pre-dehydration, filter pressing, etc., the dehydration efficiency can be improved and the moisture content in the concentrate can be reduced. (4) Slurry concentration control: Real-time monitoring and adjustment: By real-time monitoring of pulp concentration, timely adjust the amount of water added during grinding and flotation to ensure that the pulp concentration is within the optimal range. Optimize the use of reagents: During the flotation process, adjust the amount and type of reagents according to the pulp concentration to obtain the best flotation effect. (5) Operation and management: Improve operator skills: Through training and skill improvement, ensure that operators have the necessary mineral processing knowledge and skills and can operate mineral processing equipment proficiently. Introduce a modern management system: Use a digital and automated management system to monitor all aspects of the mineral processing process in real time to improve production efficiency and product quality. Strictly follow the principles of comprehensiveness and pertinence to carry out equipment transformation to ensure that the transformation work can truly improve economic benefits and production efficiency. (6) Strengthen the management of mining companies: Correct the deviations in the management and cognition of mining companies, ensure that managers have geological knowledge and mineral processing experience, and avoid non-geological personnel from conducting mineral processing according to the management model of other industries. Establish a reasonable assessment mechanism, avoid taking economic benefits as the only criterion, and ensure that the basic status of geological exploration work is valued. Through the implementation of the above measures, the links that affect efficiency in the mineral processing process can be optimized, the mineral processing efficiency can be improved, the production cost can be reduced, and the sustainable development of the mine can be achieved. (7) Continuous research and innovation: Encourage and support scientific researchers to conduct research and innovation in mineral processing technology, and continuously develop new mineral processing methods and processes. Strengthen exchanges and cooperation with other countries and regions, and introduce advanced mineral processing technology and equipment. At the same time, in view of the above-mentioned problem of low mineral processing efficiency, the introduction of MINGDE mineral processing equipment can greatly improve the mineral processing efficiency. Its value is mainly reflected in the following aspects: High-precision identification and sorting: MINGDE optoelectronic beneficiation equipment, such as the MINGDE AI sorter, can accurately identify multiple characteristics of non-metallic ores, including color, texture, shape, gloss, etc. This high-precision recognition technology enables ores to be accurately classified and screened, thereby improving the accuracy and efficiency of beneficiation. High efficiency sorting: The equipment has high-speed processing capabilities and can quickly complete the sorting of a large number of non-metallic ores. For example, the heavy-duty visible light artificial intelligence sorting machine product launched by MINGDE Optoelectronic has a sorting and processing capacity of up to 100 tons/hour, greatly improving production efficiency. Energy saving: MINGDE Optoelectronic mineral processing equipment achieves more crushing and less grinding by pre-sorting the granular ore, effectively reducing energy consumption. This optimization can not only improve production efficiency, but also reduce mineral processing costs and improve the economic and ecological benefits of the mineral processing plant. Environmental friendly: Compared with traditional physical and chemical beneficiation, the only energy consumption of photoelectric beneficiation is electricity consumption, and it has zero pollution to the environment. This green beneficiation method meets the current requirements of environmental protection and contributes to the sustainable development of mining production. High level of intelligence: With the development of computer technology and artificial intelligence technology, the intelligence level of Mingde Optoelectronics' mineral processing equipment has been continuously improved. This intelligent equipment can better adapt to the sorting needs of different types and complex ore structures, and improve the flexibility and adaptability of mineral processing. In summary, Mingde Optoelectronics' mineral processing equipment provides strong support for improving mineral processing efficiency through its advantages in high-precision identification, high-efficiency sorting, energy saving and consumption reduction, green environmental protection and high intelligence level. These advantages not only help to improve the efficiency and benefits of mining production, but also help to promote the green, intelligent and sustainable development of mining production.    

Fluorite ore, also called fluorite or soft crystal. Its main component is calcium fluoride (CaF₂) , which emits fascinating fluorescence under ultraviolet or cathode ray irradiation. The crystals of fluorite are usually larger, have a glassy luster, and have bright and varied colors, which makes it unique in the field of decoration and collection. However, due to the low hardness and brittleness of fluorite, we need to avoid violent collisions and exposure to chemicals in daily contact. In the industrial field, fluorite is the main source of fluorine and is widely used in metallurgy, chemical industry, building materials and other fields. In addition, fluorite also has good optical properties and can be used to make optical products such as glasses and lenses. In short, fluorite mine not only has unique aesthetic value, but also plays an important role in industry, scientific research and other fields. This article will take you through the main types of fluorspar and their mineral processing methods. The main types of fluorite ore can be divided according to their gangue minerals. Specifically, fluorite ore can be divided into the following types: Single type fluorite: Single-type fluorite ore is mainly composed of fluorite, with smaller amounts of other gangue minerals, such as barite, potassium feldspar, calcite, pyrite, adolite, kaolinite, etc., as well as trace amounts of phosphate-containing minerals and metal sulfides. Specifically, the grade of calcium fluoride is generally 35%-40%. A few fluorspar with more than 65% can be directly used as smelting-grade fluorspar resources, but the reserves are small and the degree of development is high. Sorting process: Hand selection is mainly used for fluorite ores where the boundaries between fluorite and gangue are very clear, and is carried out through steps such as washing, screening, and manual separation. Photoelectric separation is mainly used to sort granular ores with higher grade ores and particle sizes of 5 to 80 mm. Quartz type fluorspar ore: The main minerals are fluorite and quartz. The content of fluorite can be as high as 80% to 90%, and also contains a small amount of calcite, barite and sulfide. Since its main gangue mineral is quartz, its mineral composition is relatively simple and its purity is high. It can be used in industrial production directly or after simple treatment. Sorting process: The processing process of quartz fluorite is relatively simple and can be directly subjected to physical processing such as crushing, photoelectric sorting, and grinding. Carbonate fluorspar ore: The main minerals are fluorite and calcite, of which the calcite content can reach more than 30% and contains a small amount of quartz. Sometimes the mineral composition of such ores can be further subdivided into the quartz-calcite-fluorite type. Sorting process: Carbonate fluorspar ore has certain limitations in industrial applications. Since both fluorite and calcite in carbonate fluorspar ores have good floatability during the flotation process, conventional flotation processes and chemical systems cannot effectively distinguish between the two, resulting in calcium carbonate ( The CaCO₃) content exceeds the standard and becomes a non-standard product. Therefore, carbonate fluorspar ore is called "difficult to separate ore" by the fluorite mineral processing industry. At present, some carbonate fluorspar ores with good dissociation degree in the particle ore stage are processed by Mingde artificial intelligence sorting equipment. Pre-selecting and discarding waste to reduce the calcium carbonate content, and finally recovering the fluorspar concentrate through flotation. Barite type fluorspar ore: The main minerals are barite and fluorite, with the content of barite ranging from 10% to 40%. This type of ore is often accompanied by sulfides such as pyrite, galena, sphalerite, etc. Sometimes the quartz content also increases, forming a quartz-barite-fluorite type ore. Sorting process: After the barite type fluorspar ore is crushed, for coarse-grained ores, heavy media beneficiation methods are commonly used, such as jig beneficiation or shaking table beneficiation. When the selected fluorspar ore contains heavy metal minerals such as barite and galena, the fluorspar will be recovered as the first heavy material. For fine-grained ores, flotation is often used for separation. During the flotation process, the mixed flotation process and Na2CO3 are used to adjust the pH of the slurry, and the pharmaceutical system uses oleic acid and water glass as collectors and inhibitors respectively to obtain a mixed concentrate of fluorite and barite. The barite and fluorite are then separated by flotation. Sulfide ore type fluorspar ore: Its mineral composition is similar to quartz-fluorite, but it contains more metal sulfides, and sometimes the lead and zinc content can reach industrial grades. Sorting process: Flotation is generally used. First, a xanthate collector is used to float out the sulfide ore, and then a fatty acid collector is added to float the fluorspar. In order to suppress residual sulfide minerals and ensure the quality of fluorspar concentrate, a small amount of sulfide mineral inhibitors, such as cyanide, can be added. The selected fluorspar concentrate is dehydrated and dried to obtain the final fluorspar product. Siliceous rock type fluorite: Siliceous rock type fluorite is formed by sedimentation. This type of fluorite ore is usually distributed in shale, mica quartz and other siliceous rocks in the form of fine-grained disseminated, cement-like, strip-microlayered, lumpy, and oblate lens shapes. Sorting process: After the raw ore is crushed and screened, the coarse-grained ore is generally sorted by heavy media, and the fine-grained ore is sorted by a jig or shaker.  When the selected fluorite ore contains heavy metal minerals such as barite, sulfite, galena, etc., fluorite is recycled as the first heavy object. Sedimentary fluorite: As for carbonate fluorite among sedimentary fluorite, fluorite is distributed in fine granules in limestone and marble, and forms a granular co-bonding mosaic structure or metamorphic structure with calcite or dolomite. The mineral composition of sedimentary fluorspar deposits is relatively complex and may contain a variety of impurities and associated minerals, so more complex mineral processing and purification processes are required before industrial application. Sorting process: Due to the complexity of its mineral composition, sedimentary fluorite may need to adopt more complex processes and technologies during processing, such as flotation, gravity separation, etc. Generally speaking, the sorting process of fluorspar ore may vary depending on the nature of the ore, the performance of the beneficiation equipment and the beneficiation objectives.  Therefore, in practical applications, appropriate sorting processes and methods need to be selected according to specific circumstances,equipment, and at the same time make appropriate adjustments and optimizations to the process flow to achieve the best mineral processing effect.

China's high-purity quartz raw material ore to vein quartz and crystal-based, total resources of 6.85 million tons, of which the crystal resources are only 0.69 million t. Mainly distributed in Hubei Herb Chun (Ling Qiu Mountain quartz ore SiO2 content of 99.35%), Jiangsu Donghai (SiO2 content of 99.19%), Jingde, Anhui (version of the book of the township of Longchuan veins of quartz ore SiO2 content of 99.01%) and Taihu Lake, and other areas, of which the Donghai, Jiangsu (SiO2 content of 99.19%), Anhui Jingde (Banshu Township, Longchuan vein of quartz ore SiO2 content of 99.01%) and Taihu Lake. etc., among which the crystal quality of Jiangsu Donghai is the most superior, but the amount of reserved resources is close to depletion. In addition, there are also distributed in Anhui Fengyang, Jiangsu Xinyi, Xinjiang Altay area. Quartz ore from the SiO2 purity and the content of impurity elements (FeK, Na, Li, Ca, Mg, etc.), quartz can be divided into ordinary quartz and high-purity quartz. Generally speaking, quartz sand with SiO2 content higher than 99.9%, impurity content of Al, Fe, etc. less than 20ppm, and impurity content of K less than 1ppm is defined as high purity quartz. Depending on the purity, we can further classify high purity quartz as low end (3N), mid-end (4N), mid-high end (4N5), and high end (4N8 and above). Different purity of quartz specific applications are different, 3N below the ordinary quartz used to manufacture glass, refractory materials, etc. 3N grade used to manufacture silicate system chemical materials, 4N grade used in electronic packaging and other fields, 4N8 used in photovoltaic, communications, 5N grade used in semiconductor, chip. From the point of view of application, semiconductor and photovoltaic for the world's largest demand for high-purity quartz sand two industries, the product added value is higher. The semiconductor and new energy industry is the core strategic industry of each country, high purity quartz as a key basic material, preparation technology and export is strictly protected and restricted. High purity quartz raw ore is generally from crystal, vein quartz, granite pegmatite and other ores as raw materials after the purification of a mineral product.Its purification process is more complex, usually includes the following main links: pretreatment, physical treatment and chemical treatment of three processes. 1. Pre-treatment stage: Crushing and grinding: the quartz raw ore is crushed and finely crushed, and then ground to the required particle size for subsequent impurity removal and selection operations. Scrubbing: Remove thin film iron, clay and other easily dislodged impurities from the surface of quartz sand by mechanical scrubbing or ultrasonic scrubbing.    Hand Selection or Picking: Manual selection of obviously visible off-color particles or impurities. Magnetic Separation: Use magnetic separator to remove magnetic impurities in quartz sand, such as hematite, limonite and black mica. 2. Physical sorting: Color separation: using photoelectric technology to identify minerals of different colors and remove colored impurities. Flotation: Add chemicals in the solution, so that the impurity minerals and quartz sand due to the different surface properties to achieve separation. 3. Chemical treatment: Acid leaching: The quartz sand after physical purification is immersed in an acidic solution (such as hydrofluoric acid, hydrochloric acid or other acids) to dissolve the alkali metals, alkaline earth metals, and other impurities insoluble in water but soluble in acid encapsulated inside or on the surface of the quartz particles. Alkali treatment: For certain specific types of impurities, alkali treatment may also be required. Chlorination Roasting: High temperature chlorination roasting is sometimes used to remove some of the impurities that are difficult to get rid of with acid. 4. Subsequent treatment: Washing: After acid leaching, the quartz sand is washed several times to remove residual acid and dissolved down impurities. Dewatering: Use filter or centrifuge to dewater the washed quartz sand. Drying: The dewatered quartz sand is dried to ensure that the product is free of moisture and to prevent secondary contamination or precipitation of impurities caused by moisture. Fine grading: According to the purity requirements of the final product, fine grading and screening may also be carried out to ensure that the quartz sand particle size is uniform and in line with quality standards. Through the above series of processes, the quartz sand can be purified to a high purity level of silica content of 99.9% or more, to meet the requirements of high-end applications. It is worth noting that the actual production process of the specific purification process may be adjusted and optimized according to the characteristics of the quartz ore, the type of impurities and the final product quality requirements and other factors. Through the above series of processes, the quartz sand can be purified to a high purity grade with a silica content of 99.9% or more to meet the requirements of high-end applications.It is worth noting that the actual production process of the specific purification process may be adjusted and optimized according to the characteristics of the quartz ore, the type of impurities and the final product quality requirements and other factors. Through these complex and fine purification processes, the content of gas-liquid inclusions and homogeneous impurities in quartz sand can be effectively reduced, so as to obtain high-purity quartz sand raw materials required for the manufacture of high-end quartz crucibles. Quartz crucibles are usually designed with inner and outer double-layer structure to meet different functional requirements. The inner layer of quartz crucible requires more uniform particle size distribution of high purity quartz sand, generally requires the particle size between 0.1~0.3mm, and the cumulative mass fraction in the particle size range should be greater than or equal to 90%, and the purity is required to reach more than 5N (SiO2=99.998%). At the same time, the inner layer of quartz crucible has more strict requirements on the gas-liquid inclusions content of high-purity quartz sand, which needs to be controlled at a lower level, and the content of these elements should be as low as possible to ensure the quality and stability of the crucible. The inner periphery process mainly refers to the refining treatment of the inner wall of the crucible, which requires extremely high purity and finish, because it is the part that is in direct contact with the molten silicon, and any impurity may affect the quality of the monocrystalline silicon. Highly homogeneous and pure inner layers are achieved through advanced melting technologies and precise molding processes, such as the centrifugal molding method, to ensure that a stable temperature environment is provided and contamination is prevented during the crystal growth process. Products such as quartz crucible outer coatings, quartz tubes, quartz rods, quartz boats and quartz ingots are available up to 4N5. More attention is paid to the overall mechanical strength and thermal insulation of the crucible. For example, the outer structure needs to be sufficiently resistant to thermal shock and well insulated to avoid excessive heat loss or uneven heating that could cause the crucible to break. To ensure these properties, the outer layer of quartz may not need to be as pure as the inner layer, but the same stringent manufacturing process control is required. Quartz crucibles are mainly used for: 1. monocrystalline silicon wafer production: in the photovoltaic and semiconductor industries for pulling large diameter monocrystalline silicon rods, an important step in the manufacture of highly efficient solar cells and integrated circuit chips. 2. Laboratory high temperature experiments: used for melting samples and high-temperature reaction vessels in the fields of material science, geology and mineral analysis. 3. Other material processing and analysis under high temperature environment. At present, the raw materials used for high purity quartz sand in China are mainly pegmatite-based, which is mainly characterized by large-size natural crystals embedded in the rock matrix, which are mainly dominated by quartz, feldspar and mica.
