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.) Sources

gravity concentration, depends on the high specific gravity of the barite to separate it from the gangue components found in the ore. Both of these methods were tested in the metallurgy laboratory of the New Mexico Bureau of Mines and Mineral Resources, using barite samples taken from El Cuervo Butte.

Determination of specific gravity. Barite samples of 15.36 g and 15.38 g respectively were obtained by riffling due to the size of the density bottle. The samples were then oven-dried at 105 °C and placed in an airtight container. The density bottle was washed, dried, and its weight was determined as M 1.

Any solids-related problems encountered with these fluids are the result of depending entirely on drilled solids to achieve densities in excess of 9.4–9.6 lb/gal, the density of a fluid containing 9–10% low-gravity solids in freshwater. At lesser concentrations of low-gravity solids, particle size appears to be irrelevant.
