Envirogulf Consulting Mining And Arsenic

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 ClAsO 4 3 and cobaltite CoAsS.. In the weathering of sulphides, arsenic can be oxidised to arsenite and arsenate.
