PTMS magnetic separation

what is magnetic separation method in hindi？

The size of quartz deposits of different geological genesis types, the composition of quartz ore, and the crystal structure, crystal chemistry, grain size and grain shape of quartz minerals are all quite different. Therefore, the industrial application of quartz has a close relationship with its mineralization type. Different mineralization types of quartz have different application characteristics.

Quartz is a hard, wear-resistant, chemically stable silicate mineral. Its main mineral component is SiO2. The color of quartz is milky white or colorless and translucent. Its hardness is 7. It is brittle and has no cleavage. Shell-like fracture. Grease gloss, density 2.65, its chemical, thermal and mechanical properties have obvious anisotropy, insoluble in acid, slightly soluble in KOH solution, melting point 1750 °C.

High-purity quartz is the main raw material for producing high-performance materials such as monocrystalline silicon, polycrystalline silicon, quartz glass, optical fiber, solar cells, and integrated circuit substrates. High-purity quartz sand is mainly used in industries such as quartz glass and IC integrated circuits. Its high-end products are widely used in large-scale and ultra-large-scale integrated circuits, optical fiber, laser, military and aerospace industries. The importance of high-purity quartz is also the preparation of metal silicon for polysilicon, making it a key raw material for crystalline silicon and its solar photovoltaic industry.

Quartz mineral resources, which can be used as industrial applications in nature, are generally referred to as siliceous materials, and are mainly composed of vein quartz, quartzite, quartz sandstone, powder quartz and natural quartz sand, as well as natural crystals and granite. Initially, “high-purity quartz raw material” is a natural quartz mineral resource that can be purified by the existing mature mineral processing technology to purify the purity of SiO2 to 99.9% and above. The purified high-purity quartz sand meets the strict requirements of the current high-tech industry. .

High-purity quartz generally uses natural crystal as raw material, and then it can be selected and purified to meet the quality index requirements. However, in the world, high-grade quartz raw materials are in short supply, natural crystal reserves are decreasing year by year, the price is expensive, and it is gradually depleted. Therefore, it is very important to replace natural crystal stones with other siliceous mineral resources. Pulse quartz, quartzite and quartz sandstone are common natural quartz mineral resources. As industrial minerals, they have been used in traditional industries such as glassware, refractory products and building materials for many years. These quartz raw materials have also become the research objects of smelting crystal substitute materials.

The size of quartz deposits of different geological genesis types, the composition of quartz ore, and the crystal structure, crystal chemistry, grain size and grain shape of quartz minerals are all quite different. Therefore, the industrial application of quartz has a close relationship with its mineralization type. Different mineralization types of quartz have different application characteristics. Therefore, how to develop and utilize according to the characteristics of different types of deposit industry quartz is related to the success or failure of quartz material technology and projects.
