Chalcopyrite

Chalcopyrite is a copper iron sulfide mineral that crystallizes in the tetragonal system. It has the chemical formula CuFeS2. It has a brassy to golden yellow color and a hardness of 3.5 to 4 on the Mohs scale. Its streak is diagnostic as green tinged black. On exposure to air, chalcopyrite oxidises to a variety of oxides, hydroxides and sulfates. Associated copper minerals include the sulfides bornite,

Pyrite an overview ScienceDirect Topics

The chemical oxidation of pyrite can follow a variety of pathways involving surface interactions with dissolved O 2, Fe 3+, and other mineral catalysts (e.g., MnO 2). Oxidation of pyrite by atmospheric oxygen produces one mole of Fe 2+ , two moles of SO 4 2 and two moles of H + for every mole of pyrite oxidized ( Nordstrom, 1982 )
