Environmental occurrence and impacts of arsenic at

Arsenic is a common element in the natural environment and is frequently a significant component in gold deposits of the western United States. Such deposits contain various forms of arsenic: arsenides, sulfides, and sulfosalts. Upon weathering such minerals routinely lower the pH of nearby waters, mobilizing arsenic and other metals. Arsenic

EnviroGulf Consulting - Mining and Arsenic

2019-1-14  Mining and Arsenic. Arsenic occurs in various mineral forms, as arsenides in sulphide minerals and as arsenates. The most common mineral is arsenopyrite (FeAsS), which is also found in arsenolite (As 2 O 3), olivenite (Cu 2 OHAsO 4), mimetite (Pb 5 Cl(AsO 4) 3 and cobaltite (CoAsS).. In the weathering of sulphides, arsenic can be oxidised to arsenite and arsenate.
