Sulfide Minerals - An Overview | Sciencedirect Topics

Copper exists in a variety of sulfide minerals, of which the most important (quantitatively) is the mixed copper–iron sulfide chalcopyrite (generally notated as CuFeS 2, though a more accurate mineral formulation is probably CuFeS 1.5, as both copper and iron occur in their more reduced ionic forms).

Ore Deposits Formed By Oxidation And Supergene Enrichment

Ore Deposits Formed By Oxidation And Supergene Enrichment

Sulfide minerals are oxidized at the surface and produce sulfuric acid, and acidified rainwater then carries the copper, as copper sulfate, down to the water table. Below the water table, where sulfide minerals remain unoxidized, any iron sulfide grains present will react with the copper sulfate solution, putting iron into solution and ...
