Country of Origin:
Baryte (BaSO4) (or Barite) is a mineral consisting of barium sulfate. It is generally white or colorless, and is the main source of barium. Barite is the unofficial American spelling. The mineral is also called heavy spar or tiff.
Its Mohs hardness is 3, the refractive index is 1.63 and it has a specific gravity of 4.3-5. Its crystal structure is orthorhombic.
Baryte that is used as an aggregate in a "heavy" cement is crushed and screened to a uniform size. Barite can increase mud density in all typesof drilling fluid systems. Most baryte is ground to a small, uniform size before it is used as a filler or extender, an addition to industrial products, or a weighting agent in petroleum well drilling mud.
Some 77% worldwide is used as a weighting agent for drilling fluids in oil and gas exploration. Other uses are in added-value applications which include the car, electronics, TV screen, rubber, and glass ceramics and paint industry, radiation shielding and medical applications (barium meals) . 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 colour.
Baryte is used in the manufacture of paints and paper. Although baryte contains a "heavy" metal (barium) , it is not considered to be a toxic chemical by most governments because of its extreme insolubility.
