high gradient magnetic separation

PTMS MAGNETIC SEPARATOR

what is magnetic separation used for?

High-purity quartz is the raw material of high-grade quartz products and the material basis of high-end products in the silicon industry. It is widely used in photovoltaic, electronic information, optical communication and electric light source industries, and plays an important role in the strategic emerging industries of new materials and new energy. .
High-purity quartz is a general term for quartz products with a purity of SiO2 greater than 99.9%. The product grade can be divided according to the purity of SiO2, that is, the low end W (SiO2) ≥ 99.9% (3N), the middle end W (SiO2) ≥ 99.99% (4N), the high end W (SiO2) ≥ 99.998% (4N8) Or according to the total amount of impurity elements such as Al, B, Li, K, Na, Ca, Mg, Ti, Fe, Mn, Cu, Cr, Ni, etc., that is, the low end ≤ 10000 × 10-6, The end is ≤100×10-6, and the high end is ≤20×10-6. Each grade of high-purity quartz can be classified into 40-80 mesh, 80-140 mesh, 80-200 mesh, and 80-300 mesh by particle size.
China has a large population and abundant industries. The demand for high-purity quartz is also very large. The industries such as photovoltaics, electronic information and high-end electric light sources have great demand for high-purity quartz. We know that it is not easy to turn quartz into high-purity quartz for photovoltaic industry. Quartz is not directly used for mining. It needs to be transformed into a series of processes. When quartz sand is used in production. Must be acid washed to reduce the iron content of quartz sand.
