Barite (BaSO4) and celestite (SrSO4) are the end-members of a nearly ideal solid solution. Most of the exploitable deposits of celestite occur associated with evaporitic sediments which consist of gypsum (CaSO4·2H2O) or anhydrite (CaSO4). Barite, despite having a broader geological distribution is rarely present in these deposits. In this …Web

Barite, also called baryte, is a non-metallic mineral product with barium sulfate (BaSO 4) 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.Web
