Copper Sulfide - an overview | ScienceDirect Topics

Copper sulfide ore, which accounts for 80% of the copper resource, is the major source for the metallic copper [1]. The major copper sulfide ores contain chalcopyrite (CuFeS 2), bornite (Cu 5 FeS 4), covellite (CuS), and chalcocite (Cu 2 S). The concentrates of copper from sulfides ores are generally performed by flotation and then processed by pyrometallurgic or …

Copper Sulfide - an overview | ScienceDirect Topics

Copper sulfide minerals require the use of acid and an oxidizing agent to break the mineral lattice and release Cu2+ into solution ( Sherrit, Pavlides, & Weekes, 2005 ). Elemental copper found in nature can be leached by either oxygen or ferric ion: (15.6a) Metallic copper: Cu + 0.5 O 2 + H 2 SO 4 → Cu 2 + + SO 4 2 − + H 2 O.
