What is Barite?
Barite (BaSO4) is a mineral consisting of barium sulfate. It is generally white or colorless, and is the main source of barium. Baryte is the British spelling. The radiating form is also sometimes refered to as Bologna Stone. Barite commonly occurs in lead-zinc veins in limestones, in hot spring deposits, and with hematite ore.
