Chalcocite Compared To Chalcopyrite Ore Processing Addresses Of Copper Ore Producing Factory In China. Depending on the type of copper-bearing minerals in the ore and the treatment processes used the concentrate contains copper from around 25 for chalcopyrite CuFeS 2 ores increasing to over 50 for bornite Cu 5 FeS 4 and chalcocite Cu 2 S ores.
Chalcocite - an overview | ScienceDirect Topics
Chalcocite and oxide minerals leach rapidly under heap leach conditions. Bornite and covellite leach much more slowly. Depending on the mineralogy of a heap, leach times may vary from ~90 days to three years. Chalcopyrite hardly reacts at all in heap leaching. Heap and dump leaching are diffusion controlled – never stone reaction-rate controlled.

Solvometallurgical process for extraction of copper from ...
Extraction of copper from sufidic ores, either by pyrometallurgy or hydrometallurgy, has various limitations. In this study, a solvometallurgical process for the extraction of copper from sulfidic ore minerals (chalcopyrite, bornite, chalcocite and digenite) was developed by using an organic lixiviant (FeCl 3 as oxidizing agent and ethylene glycol (EG) as organic solvent).

2.2. Chalcopyrite Ore Processing The first step in the chalcopyrite processing is to liberate the copper minerals and remove waste constituents such as alumina, limestone, pyrite and silica so that the copper and non-ferrous mineral values are concentrated into a product containing between 20 to 30 percent copper.

Copper extraction - Wikipedia
Supergene ores rich in sulfides may be concentrated using froth flotation. A typical concentrate of chalcocite can grade between 37% and 40% copper in sulfide, making them relatively cheap to smelt compared to chalcopyrite concentrates.
