  • How to remove iron from potassium feldspar and the beneficiation process and flow How to remove iron from potassium feldspar and the beneficiation process and flow Nov 02, 2022
    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.      
  • Mingde Artificial Intelligence Mineral Separator Do Favour to Fluorite Sorting Mingde Artificial Intelligence Mineral Separator Do Favour to Fluorite Sorting Nov 19, 2022
    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.
  • How to choose ore color separator manufacturers for mining companies How to choose ore color separator manufacturers for mining companies Jan 05, 2023
    How to choose ore color separator manufacturers for mining companies In order to improve the production efficiency  , to achieve satisfactory production results, the choice of good  equipment is very necessary, then, for the ore industry, how to choose a good ore sorting equipment?   Different places of ore, because of its ore grade, mineral structure, mineral form, mineral fugacity, and particle size and other ore properties are different beneficiation process and technical conditions are different, so the beneficiation technology can not simply apply others, but must use their own ore beneficiation test to determine whether the mineral has the value of use. Therefore, for such cases, we generally recommend that ore manufacturers bring materials or mail materials to equipment manufacturers to test whether the other party's equipment to meet their own ore products. Then visit the factory on site, listen to the technical characteristics of the manufacturer's analysis of the equipment, visit the long-term use of customers.     Stone production equipment selection should be the characteristics of the ore raw materials to determine the type of equipment, from the test or other engineering experience to obtain the index value for the calculation of the process flow, to determine the quality requirements of the combination of equipment form and configuration, to determine the production capacity of the equipment model and quantity.     In the selection of equipment priority is given to equipment that is easy to operate, reliable in operation, low energy consumption and operation and management costs, at the same time, the load factor of the equipment, the particle size of the product to be processed, the amount of variation in the grading is also an important selection factor.   On the issue of quality, we must consider the manufacturer of the production equipment, to see whether the manufacturer is a formal company, whether the strength is strong, whether the reputation is trustworthy, it is recommended that it is best to personally visit the site to see if it meets their required standards. At present, the main ore equipment is ore color separator, flotation machine, magnetic separator, etc.. Among them, ore color separator has now played a vital role in the market, and its application is increasingly widespread.       Ore color separator, the lucky star of the rise of China's mining industry. Ore color separator is the use of photoelectric principle through the color distinction of the raw ore sorting large mining technology equipment, its application not only solves the lack of operator technology and quality problems, but also greatly improve the yield of ore, thereby reducing the cost of ore, can be said to the above problem is solved.     In short, the introduction of ore color separator and the continuous development of mining production technology is quite important for the development of Chinese ore. It can not only solve the dilemma of domestic ore, but also open up a new chapter of rapid development of Chinese mining industry. Make domestic ore for imported ore to produce a strong impact, get rid of its dependence, and really achieve a new revolution of domestic ore, out of China, to the world! In this regard, ore color separator should not spare pressure, continue to develop and produce more possibilities in the field, fully support the development of domestic ore, and become the booster of a new chapter in the development of China's mining industry.
