Barite, the main ore of barium, helps in making a varied types of barium compounds. Some of these compounds are used for x ray shielding. Barite is able to block x ray and gamma ray radiations. Therefore, high density concretes are made of barite so that the x ray emissions in power plants, laboratories, and hospitals are blocked.
Barite, also called barytes or heavy spar, the most common barium mineral, barium sulfate . Barite occurs in hydrothermal ore veins , in sedimentary rocks such as limestone, in clay deposits formed by the weathering of limestone, in marine deposits, and in cavities in igneous rock.
C and the reduction time of 120 180 min, 93.5 to 96.7% of barite can be removed from the ore. The kinetic data for barite reduction showed a good fit to the chemically control model, and the rate is controlled by the surface reaction. The activation energy was calculated to be 142 kJ/mol.
