Domestic research development status of high purity quartz sand:

China is one of the countries with relatively rich quartz reserves. At present, quartz ore is well mined in Donghai, Jiangsu province, Fengyang, Anhui Province, Hong 'an, Hubei Province, Xiushui, Wuhai, Inner Mongolia other places. These areas have large quartz ore reserves, high grade easy to exploit. Most of the quartz ore mined is only used for low-end quartz products with low economic added value, such as silicon powder, glass, refractory materials, ferrosilicon, silicon carbide, fused quartz, etc.

In fact, there are many mineral sources that can be used to produce high purity quartz sand in China, but due to backward processing means the lack of basic research in earth science such as mineralogy geological genesis related to quartz glass raw material ore, the products can meet the requirements of high purity quartz raw material. At present, the middle low grade high purity quartz sand used in quartz glass in China is mostly made crystal. Crystal in China's reserves are limited, expensive, uneven texture, some mineral impurities mixed substances in the process can be removed, resulting in the production of ultra-pure quartz sand by crystal batch small, quality is stable.

Development trend of high purity quartz sand:

With the depletion of fine crystal resources, the problem of insufficient self-sufficiency of high-grade quartz sand in China mainly focuses on the improvement of geological prospecting, process mineralogy mineral processing. First of all, it is necessary to find the ore with relatively pure crystal, homogeneous in-phase replacement less gas liquid inclusion. Secondly, it is necessary to comprehensively use modern advanced physical chemical beneficiation purification technology equipment to develop efficient stable high purity quartz beneficiation purification technology. High purity quartz sand has become a strategic product of national economy.

It is urgent to seek the progress of purification technology industrial development of high-purity quartz sand ore in China realize the self-sufficiency of high-grade quartz sand in the development of quartz glass industry in China, which is of great significance to the development of relevant high-tech industry in China.
