WhatsApp: +86 18838072829Barite is a mineral composed of barium sulfate (BaSO 4 ). It receives its name from the Greek word "barys" which means "heavy." This name is in response to barite's high specific gravity of, which is exceptional for a nonmetallic mineral. The high specific gravity of barite makes it suitable for a wide range of industrial, medical, and ...
