Barite is generally white or colorless, and is the main source of barium. Baryte is the British spelling. Barite commonly occurs in lead-zinc veins in limestones, in hot spring deposits, and with hematite ore. It is often associated with the minerals anglesite and celestite. Barite has also been used in the manufacture of paints and paper. Although barite contains a "heavy" metal (barium), it is not considered to be a toxic chemical by most governments because of its extreme insolubility.
