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.
