The word barium comes from the Greek word barus, which means heavy. The common barium minerals are barite and witherite. Barite is by far the predominant barium mineral used by industry. Barytes is a naturally occurring barium sulfate with a chemical formula BaSO4 (BaO 65.7% and SO3 34.3%). Because the mineral has a high density and is chemically inert, it is ideal for use in the petroleum, automotive, and paint industries, and in other applications.
In the petroleum industry, the barite is used to make what is known as “drilling mud.” Barite and other additives in drilling mud assist in several ways during drilling. The barite serves as a weighting material that increases the hydrostatic pressure of the drilling mud and thus controls high-pressure zones that are encountered during drilling. Proper weighting prevents what industry calls a “blowout.” Because the barite is soft, it does not damage or cause abrasion problems to drilling tools such as the bits and drill pipe. Also because of its softness, it will also act much like a lubricant. Finally, because barite is chemically inert, it does not react with or interferes with other components used in the mud.
Barite is used in the industrial market in such products as traffic cones; brake linings; paint; sound-deadening materials in automobiles, golf balls, and foam; and as filler in several other products. The important uses of barytes are:
3. Barium metal recovery
7. Coal washing
9. Nuclear reactors and other radiation equipments
11. Children’s toys
