BARYTE / BARITE LUMPS
Baryte is used in added-value applications which include filler in paint and plastics, sound reduction in engine compartments, coat of automobile finishes for smoothness and corrosion resistance, friction products for automobiles and trucks, radiation-shielding cement, glass ceramics, and medical applications (for example, a barium meal before a contrast CT scan). Baryte is supplied in a variety of forms and the price depends on the amount of processing; filler applications commanding higher prices following intense physical processing by grinding and micronising, and there are further premiums for whiteness and brightness and color.[9] It is also used to produce other barium chemicals, notably barium carbonate which is used for the manufacture of LED glass for television and computer screens (historically in cathode ray tubes); and for dielectrics.
Historically, baryte was used for the production of barium hydroxide for sugar refining, and as a white pigment for textiles, paper, and paint.[2]
Although baryte contains the toxic heavy metal barium, it is not toxic because barium sulfate is extremely insoluble in water.
It is also sometimes used as gemstone.
