Leaching of Copper Sulphides SAIMM

68When considering the leaching of copper sulphides, it is very important to understand the mineralogy of the ore body because not all leaching options are suitable for all minerals. A very effective way to develop the required understanding of the mineralogy is to do test work on sitespecific ores. It is important that this test work is done on representative samples from the ore body. In addition, it is

The critical degree of mineral surface oxidation in

11Copper sulphide minerals, found in the primary and secondary enrichment hydrothermal zones, yield the most copper production throughout the entire globe. The most commonly found copper sulphides in the primary zone are chalcopyrite (CuFeS 2) and bornite (Cu 5 FeS 4) while the secondary enrichment zone hosts mainly chalcocite (Cu 2 S) and

A Review of the Flotation of Copper Minerals

74Copper is most commonly present in the earths crust as copperironsulphide and copper sulphide minerals, for example, chalcopyrite (CuFeS2), bornite (Cu5FeS4) and chalcocite (Cu2S). Copper

Carrollite is the only cobaltbearing mineral. There are four different copper sulphide minerals, i.e., bornite, chalcopyrite, chalcocite and again carrollite. The content of these four sulphide minerals varies across the samples.

The bioleaching of sulphide minerals with emphasis

2006101Enargite is a copper arsenic sulphide (Cu 3 AsS 4) that occurs frequently with chalcocite. It does not easily separate from the other sulphide minerals during flotation concentration, and thus the resulting higharsenic concentrates cannot be roasted. Heap leaching of enargiterich copper ores may be a process option.

Direct extraction of copper from copper sulfide

Copper is predominantly recovered from sulfide ores by pyrometallurgy an energy intensive process requiring capture and treatment of released SO 2. Whilst some copper ores are amenable to hydrometallurgy, chalcopyrite, the main copper mineral, is challenging to process in aqueous solutions due to surface passivation.
