metal profile: copper - metallurgy materials for all intents and purposes all sulfide-sort copper minerals, including chalcocite (cu2s), chalcopyrite (cufes2) and covellite (cus), are dealt with by refining. in the wake of smashing the mineral to a fine powder, it is then focused by foam buoyancy, which requires blending the powdered metal with reagents that join with the copper to make it hydrophobic.

chalcopyrite (copper iron sulfide) it is only 25%, compared to other copper minerals such as chalcocite, cu2s - 67%; cuprite, cu2o - 67%; covellite, cus - 50% or bornite cu5fes4 - 50%. however the large quantities and widespread distribution of chalcopyrite make it the leading source of copper. chalcopyrite is a common mineral and is found in almost all sulfide deposits.
