Sources on contamination include CO 2 (from formation, formation water, aeration at surface), overtreatment with bicarb and soda ash (for gyp or cement), thermal degradation of organic additives, and contaminated barite or bentonite. The proportion of carbonates to bicarbonates is a function of pH.
Baryte - Wikipedia
Baryte or barite (UK: / ˈ b ær ʌ ɪ t /, / ˈ b ɛər aɪ t / [citation needed]) is a mineral consisting of barium sulfate (Ba S O 4). Baryte is generally white or colorless, and is the main source of barium.The baryte group consists of baryte, celestine (strontium sulfate), anglesite (lead sulfate), and anhydrite (calcium sulfate). Baryte and celestine form a solid solution (Ba,Sr)SO 4.
Missouri Barite - DNR
Mining: Barite mining in Missouri began around 1850; however, early lead mining operations began as early as 1725 in the same area, but barite was cast aside as a waste product at that time. Barite production data has been recorded from 1872 to present. The Washington County deposit is the major source of Missouri’s barite production.
Effects of Barite Mining on Water Quality in Azara-Awe ...
The contamination by barite mining can result in profound irreversible destruction of the environment. In many cases the polluted sites may never be fully restored, because pollution is so persistent that there is no available remedy (EEB, 2000).

Asbestos Mines - Vermiculite Mining & Asbestos Exposure
Jan 29, 2019 · Mining in North America. Before asbestos mining came to the United States, it was already commonplace in Canada. Quebec was a large mining area, though mines operated in cities throughout Canada. At one point, Canada had several dozen mines in operation and was the largest exporter of asbestos to the U.S. and many other countries.
Missouri Lead Mining History by County - DNR
Missouri has been the leading producer of lead in the United States for well over a century and has also been the worlds leading producer. Early mining in the entire southeast Missouri area was of oxidized ores, primarily the lead carbonate mineral cerussite. Mining moved onto galena when the more easily smelted cerussite was depleted.
