Barite, frequently termed barytes or heavy spar , is a sulfate of the metal barium. The commercial use of barite, as such, is largely dependent on the fact that it is a This is the raw material for the manufacture Hof ground barite, lithopone, 3 and in jigs or log washers to remove clay, iron oxides, and other impurities. 2.Pure barium sulfate has a specific gravity of 4.50 g cm 3, but drilling grade barite is expected to have a specific gravity of at least 4.20 g cm 3 to meet API specifications. Contaminants in barite, such as cement , siderite , pyrrhotite , gypsum , and anhydrite , can cause problems in certain mud systems and should be evaluated in any quality.
