A Review on Novel Techniques for Chalcopyrite Ore

2012-1-1  Chalcopyrite ores are usually processed by means of hydrometallurgical or pyrometallurgical processes, but due to environmental aspects and the possibility of increased exploitation of mixed and lower grade ores and relatively small isolated deposits, there has been a worldwide upsurge of interest in the hydrometallurgical processes of this ore as compared to pyrometallurgy.

Characterization of a Chalcocite Copper Ore Deposit

2018-2-3  The chalcocite enrichment blanket is composed of two to three layers of higher grade ore (0.4 to 1.3 pct Cu), from 6 to 12 m thick, separated by thinner layers of lower grade ore (<0.2 pct Cu). The average grade in the enrichment zone is 0.41 pct Cu.

CHALCOCITE (Copper Sulfide) Galleries

Chalcocite is an important copper mineral ore. It has been mined for centuries and is one of the most profitable copper ores. The reasons for this is its high copper content (67% atomic ratio and nearly 80% by weight) and the ease at which copper can be separated from sulfur.

Biogenic sulphide for cyanide recycle and copper

Many complex-ore gold deposits with cyanide-soluble copper minerals such as chalcocite, covellite, bornite, cuprite, malachite and azurite are now being considered for processing. In some cases the ore is not currently being mined largely due to the various issues associated with the cyanide-soluble copper minerals in the ore, which results in low

2019-7-9  The chalcocite is more oxidized than the chalcopyrite, copper ions enter the slurry, complicating the flotation process and increasing the difficulty of separating. The collectors of chalcopyrite are mainly xanthate and Aeroflot. The effective inhibitors are sodium sulphate, sodium sulfite, potassium ferricyanide and potassium ferrocyanide.
