Barite belongs to non metallic mineral products whose main composition is BaSO4 .Pure barite is white and shiny .It is also gray, light red, light yellow because of impurities.It has the Mohs hardness of 3 ~ 3.5 and the proportion of 4.5. Barite has the properties of chemical stability, insoluble in water and hydrochloric acid, non-magnetic and non-toxicity.

• Barite is an important non- metallic mineral raw material.It has wide industrial uses, such as drilling mud weighting agent, Lithopone pigment,barium compound,filling industry,anti-ray cement,mortar and concrete etc. 
• As a filling material,barite is also used in the field of paper-making industry,rubber and plastics industry since it can improve the hardness,insulation and aging resistance of rubber and plastics products.
