Mica's Mohs hardness is 2-3.5, ultrafine vertical mill production line can be used in building materials, fire, fire extinguishing agent, welding electrodes, plastic, electrical insulation, paper, asphalt paper, rubber, pearlescent pigments and other chemical industry. Mica can be divided into muscovite, biotite and lithium mica three categories. With the improvement and upgrading of technology, the world of mica powder processing status is also improving.

China: China is rich in mica resources, nearly all over the country; the total output is about 3 million tons, accounting for about 10% of the world’s total output. The main types are muscovite and phlogopite, which have been exploited and used more than 30 mines. The main producing areas are Xinjiang Altai muscovite ore, Sichuan Danba muscovite ore deposit, Inner Mongolia Guiguula muscovite mine, Shaanxi Danfeng Muscovite ore, Jilin Jimei gold mica mine, Henan Zhenping gold mica ore and Hebei Quyang muscovite mine and so on.
