Barium is present as a trace element in both igneous and sedimentary rocks. Although it is not found free in nature (US EPA, 1985a), it occurs in a number of compounds, most commonly barium sulfate (barite) and, to a lesser extent, barium carbonate (witherite).

1.4 Environmental fate. Barium in water comes primarily from natural sources. The acetate, nitrate and halides are soluble in water, but the carbonate, chromate, fluoride, oxalate, phosphate and sulfate are quite insoluble. The solubility of barium compounds increases as the pH level decreases (US EPA, 1985a).Web

One hundred and sixty four barite deposits and occurrences have been documented in South Australia, with a total recorded production of ~870 000 t (December 2013).

Barium minerals are dense (e.g., BaSO 4, 4.5 grams per cubic centimetre; BaO, 5.7 grams per cubic centimetre), a property that was the source of many of their names and of the name of the element itself (from the Greek barys, "heavy").Ironically, metallic barium is comparatively light, only 30 percent denser than aluminum.Its cosmic abundance is …Web

Named from the Greek word meaning "heavy," barium is a soft, silvery-white metal. It is an active metal, reacting with air, water, acids and bases. Because it is insoluble in the body, barium sulfate is used as an x-ray tracer for the stomach and intestines. Barium is also used in drilling fluids for oil exploration, as well as in paints ...Web
