| SULFIDES | 1. Copper Sulfide The sulfide minerals of copper such as chalcopyrite (CuFeS2), covellite (CuS), chalcocite (Cu₂S), bornite (Cu, FeS,), cubanite (CuFe₂S,), and digenite (Cu, S,) are not as such soluble in dilute H₂SO,. However, they readily dissolve in this acid in the presence of oxidizing agents such as oxygen, ferric ion, and bacteria. In common practice, low-grade ores are |
