Barite is typically white/grey in appearance but can vary from yellow, brown, red, and even black due to impurities. Barite's Mohs hardness is 3.0 to 3.5, making it a relatively soft mineral. It is chemically inert and insoluble, which along with its high density, lends itself to a variety of applications.

Barite is the principal ore of barium. Barium has very high number of applications. It is known to have more than 2000 industrial uses. However, the majority of barite mined is not used to extract barium. It is valuable in its native form because of high density. It is mostly used by oil & gas industry as an ingredient of drilling mud.
each ground low grade barite particle such that the discrete particles have a specific gravity of 4.10, or 2) that the quartz (and other low gravity contaminants) exists as separate particles with a specific gravity of +/- 2.6 and that pure barite particles exist as separate particles with a specific gravity of 4.5.
Due to its low cost and high selectivity in the concentration process, gravity methods such as jigs for coarse barite ores and shaking tables for the concentration of fine barite ores are generally used. However, the very fine barite minerals (under 75 m) can not be concentrated efficiently using these gravity methods.
