The following editor talks about the research and development status of domestic high-purity quartz sand:

China is rich in quartz reserves. At present, the areas where quartz mines are better exploited include Donghai in Jiangsu, Fengyang in Anhui, Hong'an in Hubei, Xiushui in Jiangxi, and Wuhai in Inner Mongolia. These areas have large reserves, high grade, and easy access. However, due to the backward processing and utilization technology of domestic quartz sand, most of the quartz ore mined is only used as 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. However, due to the backward processing methods and the lack of basic research on the mineralogy and geological origin of quartz glass raw materials, the products cannot meet the requirements of high-purity quartz raw materials. . At present, most of the low- and medium-grade high-purity quartz sand used in our country's quartz glass is made from crystal. The reserves of crystal in our country are limited, the price is expensive, and the texture is uneven. It is impossible to remove some mineral impurities and mixed materials in the process, resulting in small batches of ultra-pure quartz sand produced from crystals and unstable quality. The development trend of high purity quartz sand:

With the depletion of good crystal resources, solving the problem of insufficient self-sufficiency of quartz sand in my country is mainly focused on the improvement of professional technology such as geological prospecting, technological mineralogy and mineral processing. First, it is necessary to look for ore with relatively pure crystals, homogeneous replacement of similar substances and less gas-liquid inclusions. Second, it is necessary to comprehensively adopt modern advanced physical and chemical beneficiation and purification technologies and equipment to develop efficient and stable high-purity quartz beneficiation and purification technologies. High-purity quartz raw material sand has become a strategic product of the national economy.

Efforts to seek the progress of my country's high-purity quartz sand ore purification technology and industrial development, to realize the self-sufficiency of quartz sand is an urgent need for the development of my country's quartz glass industry, and is of great significance to the development of my country's related high-tech industries.

The above is the research and development status of high-purity quartz sand that the editor tells you. I hope that a simple description can help you understand quartz sand. The content is for your reference only. If you need to know about it, please contact our manufacturer.
