Barite is a non renewable resource and one of China's export dominant mineral products. It is widely used as a weighting agent for oil and gas drilling mud, and its consumption in barium chemical industry, filler and other fields is increasing year by year. China is rich in barite resources, which are distributed in 21 provinces (regions) of China, with a total reserve of 360 million tons of ore, ranking first in the world.
Barite,The chemical composition of barite is BaSO4, and the crystal belongs to orthorhombic (rhombic) system of sulfate mineral. It is usually in the form of thick plate or columnar crystal, mostly dense block or plate, granular aggregate. When it is pure, it is colorless and transparent. When it contains impurities, it is dyed into various colors. The stripes are white and the glass is glossy. It is transparent to translucent. The three groups have complete cleavage, and the included angle is equal to or close to 90 °. Mohs hardness 3-3.5, specific gravity 4.0-4.6.
