Barite Mineral | Uses and Properties
Barite is also a common mineral in hydrothermal veins and is a gangue mineral associated with sulfide ore veins. It is found in association with ores of antimony, cobalt, copper, lead, manganese, and silver. In a few locations barite is deposited as a sinter at hot springs.

The ore body is brecciated (fragmented) and may represent the filling of a volcanic neck or pipe. Ore occurs as coatings on boulders within the brecciated ore body. Mineralization includes galena (lead sulfide), sphalerite (zinc sulfide), and pyrite (iron sulfide). Silver occurred in the galena ore at about 68 ounces of silver per ton of galena.
Acanthite Composition, Characteristics, Properties, Uses
Acanthite and Argentite are often used interchangeably. Both are ores of silver sulfide. Above 173 oC, Argentite is a form of Silver Sulfide. Below this temperature, Argentite changes to Acanthite. At room temperature, Ag2S actually stands for Acanthite. Acanthite Versus Galena. Acanthite and Galena are two most important ores of Silver.
