Barite or Baryte is a mineral consisting of Barium sulfate and is generally white or colorless. The baryte group consists of baryte, celestine, anglesite and anhydrite. Baryte commonly occurs in lead-zinc veins in limestones, in hot spring deposits, and with hematite ore. It is used in the manufacture of paints and paper. Although Barite contains a ‘heavy’ metal, Barium, it is not considered to be a toxic chemical because of its extreme insolubility.
