Arsenic

The arsenic was recovered mostly during mining operations, for example the production from Peru comes mostly from copper mining and the production in China is owing to gold mining. On roasting in air of arsenopyrite, arsenic sublimes as arsenic (III) oxide leaving iron oxides[16], while roasting without air results in the production of metallic arsenic.
