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.

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.

Mingde photoelectric ore color sorter to solve the ore sorting problem Along with the high-quality economic development and the continuous upgrading of industrialization development, more and more users need to use intelligent ore color sorter. From the rough economic development to a higher level of development requirements cover various fields such as resources and agriculture. Such as the mining of mines, the policy side will become increasingly strict. The old exploitable high-grade mines are almost finished, and most of the remaining mining rights have poor taste in ore quality, and the impurity content of the ore can be mined and used more and more. The standard of living has increased significantly, which has also lead to an increasing demand for resources and higher quality requirements, which cannot be met by human sorting, nor is it realistic. First of all, labor costs are getting higher and higher, enterprises are heavily burdened with labor, and frequent staff turnover also causes unstable production, which can only be accomplished by automated sorting equipment so that enterprises can have room for survival; secondly, the sorting process of ore is prone to a series of problems such as pneumoconiosis, social welfare and safety, etc. In addition, some too small distinctions or too small particles cannot be sorted manually, and can only be sorted with the help of intelligent ore color sorter to Improve the sorting accuracy. For a long time, Mingde Optoelectronics has been improving the competitiveness of the company in terms of products, technology and services, deeply combining with the actual scenarios of mining customers, solving the requirements of ores in all aspects, and has developed a number of color sorting machine series for the mining industry, comprehensively covering the sorting needs based on process, particle size, properties, etc., creating a unique ore sorting product matrix in the industry, realizing most non-ferrous metal ores and some We have created a unique product matrix for ore sorting in the industry, which can achieve efficient sorting of most non-ferrous metal ores and some non-metallic ores, meet the needs of various beneficiation scales, reduce manual operation costs, effectively reduce waste water and carbon dioxide emissions, fully conserve resources and protect the environment, and achieve efficient revenue generation for mining enterprises while striving to create a green mine and a smart mine.

The advantages of double-layer Ore color sorter in wet Ore color separation according to raw materials can be divided into ore dry selection and wet selection water separator, users can choose the type of ore color separator according to their site conditions, Mingde photoelectric double layer wet selection color separator can do dry and wet universal. The principle of double-layer crawler type wet sorting color sorter is as follows.        In the wet state after the crushing of the original ore, the color difference between the finished product and impurities is relatively large, and the ore sorting effect is better. And wet sorting can reduce the drying process, saving equipment investment to increase revenue.        Usually dry separation of ore will cause dust, can not meet the requirements of environmental protection, ore wet separator can avoid color separation of ore when the dust generated to ensure environmental protection requirements.        Double-layer double mirror ore wet separator can effectively identify bad material in all aspects by two sets of high-definition cameras on the top and bottom, and the selection rate is more than 99%.       Double-layer double mirror ore wet separator  

How to sort Associated non-metallic fluorite   According to the different components of fluorite ore associated minerals, fluorite can generally be divided into monotypic fluorite, quartz-type fluorite, sulfide-type fluorite, calcite-type fluorite, barite fluorite, silica-type fluorite, carbonate-type fluorite, etc. As an important non-metallic mineral raw material, fluorite is widely used in chemical, steel, aluminum, ceramics and other industries, and is the main raw material for the preparation of fluorine, with the development of science and technology, fluorite in With the development of science and technology, the use of fluorspar in high-tech industries has gradually increased and become an important strategic mineral resource. Then how to effectively improve the taste of fluorspar is vital to the utilization of fluorspar.     So how to effectively improve the taste of fluorspar ore, Hefei Mingde photoelectricity recommended the use of artificial intelligence sorting machine. For the situation of associated fluorite ore, ordinary ore color sorter has been unable to complete the fluorite color separation, because the traditional photoelectric color sorter can only rely on a simple color difference for selection, the more obvious the color difference the better the sorting effect, the logic of a single criterion. Mingde photoelectric launch artificial intelligence sorting machine is the use of AI deep convolutional neural network (CNN) and other artificial intelligence means of material image analysis and processing technology, AI photoelectric sorting technology can automatically extract the multi-dimensional characteristics of the material, such as texture, shape, color, texture, luster, etc., greatly enhance the sorting effect, expand the sorting scene and material types, to meet the market diversification and personalized sorting requirements. Solve the current color sorting machine market color sorting material is limited by the problem.     Here is a look at the following case of the Mingde photoelectric artificial intelligence sorting machine sorting non-metallic associated fluorite ore, throwing miscellaneous stone, throwing silicon, throwing calcium carbonate, improve the taste of fluorite.                                                           Fluorite raw ore       Finished fluorite ore                                                                          Fluorite ore waste rock      

In winter, what should be paid attention to the ore color separator?   Mingde photoelectric ore color sorter is divided into quartzite color sorter, potassium feldspar color sorter, talc color sorter, fluorite color sorter, wollastonite color sorter, calcium carbonate, barite and other non-metallic ore color sorter and metal ore color sorter according to the different needs of ore sorting. 2021 is affected by La Nina, it may be a cold winter. For the use of ore color sorter in winter, Mingde photoelectric gives the following small suggestions.      1, ore color sorter winter use tips. Each shift should open the ore color sorter for preheating half an hour before work, the working environment should be kept above +5℃, especially in the northern region must pay attention to the working environment. (1) In the cold winter, the ball valve should be opened slowly to prevent the high-speed airflow from freezing the pipe. (2) After each shift, the residual gas and water in each equipment should be emptied strictly to prevent the phenomenon of icing.     2、 How to judge whether there is blockage in the gas supply pipe, Mingde photoelectric tips.  Ore color sorter in the working process, the air compressor again when starting, need to pay attention to the color sorter side air inlet pressure table and the air compressor indicates the same air pressure value. If lower than the value of the compressor pressure table, that indicates that the pipeline is blocked (dirty plug or ice plug), please clean the pipeline and each filter element.
