    Arsenic comprises about 1.5 ppm (0.00015%) of the Earth's crust, and is the 53rd most abundant element. Typical background concentrations of arsenic do not exceed 3 ng/m in the atmosphere; 100 mg/kg in soil; and 10 μg/L in freshwater. Minerals with the formula MAsS and MAs2 (M = Fe, Ni, Co) are the dominant commercial sources of arsenic, together with realgar(an arsenic sulfide mineral) and native (elemental) arsenic.

  • EnviroGulf Consulting - Mining and Arsenic

    Mining and ArsenicSources of ArsenicTechnical ServicesConsulting ServicesRelevant ExperienceArsenic 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 (As2O3), olivenite (Cu2OHAsO4), mimetite (Pb5Cl(AsO4)3and cobaltite (CoAsS). In the weathering of sulphides, arsenic can be oxidised to arsenite and arsenate. Arsenic oxide is also formed as a by-product of copper, lead and nickel smelting.

    A lot of arsenic was produced here In the 1870s, a handful of mines in Cornwall and Devon produced over half the world's arsenic. It was a by-product of tin and copper processing and was mainly used in paint, weedkillers and insecticide. It was condensed and collected in long flues or labyrinths, like the one in this photo at Botallack.
