Barite is a mineral composed of barium sulfate (BaSO4). It receives its name from the Greek ord "barys" which means "heavy." This name is in response to barite's high specific gravity of 4.5, which is exceptional for a nonmetallic mineral. The high specific gravity of barite makes it suitable for a wide range of industrial, […]
