By Ralls Eric. Earth staff writer. 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 ...

Barite, barites, or heavy spar, a white, yellow, blue, red, or colorless mineral. It is a sulfate of barium, BaSO 4, found in nature as tabular crystals or in granular or massive form and has a high specific gravity. The mineral is widely distributed throughout the world. It often occurs in veins with lead and zinc minerals.

The main method of barite beneficiation is gravity beneficiation, so the beneficiation process of barite is also based on gravity beneficiation. The use of gravity beneficiation methods and equipment to process barite is also the most economical, ideal, and most effective beneficiation method at present. ...
