Effect of Cyanide on Steel and How Iron Minerals are

The three most important iron minerals in cyanidation are pyrite, marcasite and pyrrhotite. These minerals decompose in cyanide solutions in the order given, i.e., pyrite is the most stable and pyrrhotite the least. Pyrite, FeS2, is insoluble in hydrochloric acid, but decomposes readily in nitric acid, most of the sulphur going to sulphuric acid.

ARSENOPYRITE (Iron Arsenide Sulfide)

Although an ore of arsenic, it is not intentionally mined for that reason. In processing the ore of other elements some arsenopyrite is "accidentally" included and gives off its arsenic as fumes that are then recovered. This "accidental" source supplies most of the world's needs in arsenic. Arsenopyrite makes attractive mineral specimens as well.
