Quartz sand is a quartz particle produced by crushing quartz stone. Quartz stone is a non-metallic mineral, a hard, wear-resistant, and chemically stable silicate mineral. The color of quartz sand is milky white, or colorless and translucent, with a Mohs hardness of 7. Quartz sand is an important industrial mineral raw material, non-chemical dangerous goods, widely used in glass, casting, ceramics and fireproof materials, smelting ferrosilicon, metallurgical flux, metallurgy, construction, chemical industry, plastics, rubber, abrasives, filter materials and other industries. Quartz sand is also the main raw material of precipitated silica!

The article "Cost-driven, the price of precipitated silica is about to rise again" mentioned that the main reason for the recent price increase of major domestic precipitated silica manufacturers is due to the price increase of raw materials such as soda ash and sulfuric acid. It did not mention the core raw material-quartz sand. This is because quartz sand is rich in resources, widely distributed and relatively concentrated, and the price is relatively stable. The price will only increase to a certain extent until around 2021.

Quartz sand is the most common and widely used non-metallic mineral raw material in nature. There are many types of quartz sand deposits in my country, mainly including quartzite, quartz sandstone, natural quartz sand and vein quartz. However, its quality is not high, most of which are quartzite, quartz sandstone and natural quartz sand. The three account for 99.07% of my country's quartz resources, while high-quality vein quartz only accounts for 0.93% of China's quartz resources.

From a domestic perspective, Lianyungang in Jiangsu, Fengyang in Anhui, Lingshou County in Hebei, Heyuan in Guangdong, and Linyi in Shandong are the main production plants for quartz raw materials, occupying 80% of the country's market. Their raw materials are famous for their high purity and large output. Fengyang quartz sand is the most prestigious place, while Ahu town quartz sand is the best quality.
