2022-2-11 · Arsenic (As) is classed as a semi-metal, or metalloid. In nature it is commonly found as a metal in low levels in most soils and in higher concentrations associated with some copper, lead and zinc ores. The most common arsenic mineral is arsenopyrite, a compound of iron, arsenic, and sulfur. Type. Crystal System.Arsenic Mining Processing2021-12-28 · Arsenic in Waste from Coal Mining, Processing, and Storage Mining operations in the United States generally must meet water-quality stan-dards for discharge of mine water. In some abandoned mines or undisturbed pyrite-rich strata, however, decomposition of pyrite in coal and rock can lead to dispersal of arsenic to the environment.
