Barium carbonate | BaCO3 - PubChem

The barite suspensions used in the oil well drilling industry can destabilize when soluble materials such as gypsum are present in the mud. The presence of gypsum leads to coagulation and a loss of consistency in the drilling muds. When added to the muds, barium carbonate precipitates the gypsum and prevents destabilization of the barite ...

WRIR 02-4045, Part2 - USGS

The solubility of barium is primarily controlled by barite (barium sulfate) (Hem, 1985), so the absence of sulfate may be responsible for the relatively high concentrations observed in the waters. Environmental Isotopes. Isotopes are atoms of the same element that have the same numbers of protons and electrons but different numbers of neutrons.

Central Missouri Barite and Lead District Lead was the principal product of the Central Missouri Lead and Barite District from 1830 to 1910; there was also minor zinc production. After 1910, the district produced barite with lead as a by-product (Kiilsgaard et al, 1967; Brobst and Wagner, 1967). Production ended in the 1950s.
