In 2018, the market scale of China's quartz sand exceeded US $3 billion, and the demand for high-purity quartz sand grew rapidly
Quartz sand is an important industrial mineral raw material, non chemical dangerous goods, widely used in glass, casting, ceramics and refractories, smelting ferrosilicon, metallurgical flux, metallurgy, construction, chemical, plastic, rubber, abrasive and other industries. In the market, silica sand is the most basic quartz mineral product, which can be divided into quartz sand, quartz powder, ultra-fine silica powder, cristobalite, high-purity quartz, etc. according to the different grade and processing degree of the ore body itself. Quartz sand mainly refers to river sand, sea sand and weathered sand with more silicon dioxide. In addition to the main component silicon dioxide, it also contains iron oxide, clay, mica and organic impurities. It is mainly used as raw material of glass industry and ceramic industry, and flux of metallurgical industry. Fine quartz sand can be used as abrasive for grinding glass, etc. The main products of quartz sand...
