Barite is a non-metallic mineral which is simply barium sulfate (BaSO 4) and is largely used by the oil and gas industry as a weighting agent in drilling mud during drilling operations. The specific gravity of barite should range from 4.1 to 4.6 to be applicable as a drilling mud additive.

Barite (spelled baryte in British publications) was named from the Greek word baros which means weighty, a reference to its unusually high specific gravity. (Specific gravity is a mineralogist's measure of the density of a mineral; this is done by comparing the weight of the mineral to the weight of an equal volume of water.)
