Barite is the most common mineral of barium, and its composition is barium sulfate (BaSO4). It is produced in low-temperature hydrothermal veins, such as quartz-barite veins, fluorite-barite veins, etc., and often coexists with galena, sphalerite, chalcopyrite, cinnabar, etc. Colorless and transparent, its color often changes due to impurities and admixtures, and it actually appears in white, gray, light yellow and other colors.
