Barite, also called baryte, is a non-metallic mineral product with barium sulfate (BaSO4) as the main component. The name of barite comes from the Greek word barys, which means heaviness and implies the weight of this mineral. Because the specific gravity of barite is as high as 4.5, which is very rare in non-metallic minerals.
