Barite is the primary, naturally occurring, barium-based mineral. Barium, atomic number 56, derives its name from Greek and means heavy. Barite is also known as baryte. The primary countries in which commercial deposits of barite are currently found are the United States, China, India and Morocco. Barite’s high density and chemical inertness make it an ideal mineral for many applications.

The chemical formula for barite is BaSO4. To be economically viable for extraction, barite usually needs to be the predominant material in a deposit. The types of deposits in which it is normally found include vein, residual, and bedded. Vein and residual deposits are of hydrothermal origin, while bedded deposits are sedimentary.
