Chalcocite, sulfide mineral that is one of the most important ores of occurrences include deposits of sulfide minerals at Ely, Nev., and Morenci, Ariz., where other components of the original rock have been dissolved away; it is also found with bornite in the sulfide veins of Tsumeb, Namibia, and Butte, Mont.

Copper is found in many minerals which occur in deposits large enough to mine. These include: azurite, malachite, chalcocite, acantite, chalcopyrite and bornite. Most copper comes from chalcopyrite. The world's leading producer of copper is Chile, followed by the and Peru.

13/06/2016 · When chalcocite is leached with ferric sulphate onehalf of the copper dissolves rapidly leaving a residue approximating CuS which dissolves much slower; with bornite the copper is attacked preferentially to the iron; while with chalcopyrite the mineral dissolves as chalcopyrite; that is, at any stage in the dissolution (up to an extraction of ...

Bornite Bornite is an important copper ore (it is both a copper and iron sulfide mineral). It forms brittle, granular, or compact masses that on fresh fractures are metallic and brassy. Upon exposure to moisture, bornite tarnishes to a purplish iridescence, for which reason it is commonly called peacock ore.

Bornite is an important copper ore mineral and occurs widely in porphyry copper deposits along with the more common chalcopyrite.

Copper is most commonly present in the earth's crust as copper–iron–sulfide and copper sulfide minerals, for example, chalcopyrite (CuFeS 2), bornite (Cu 5 FeS 4), and chalcocite (Cu 2 S) The concentrations of these minerals in an ore body are low Typical copper ores contain from 05% Cu (openpit mines) to 1−2% Cu (underground mines)

Copper ores. The main copper sulphide minerals are chalcopyrite (CuFeS2) chalcocite (Cu2S), covellite (CuS), bornite (Cu5FeS4), tetrahedrite ((Cu,Fe)12Sb4S13) and enargite (Cu3AsS4). The largest source of copper is from porphyry ore deposits in which one or a combination of the aforementioned minerals occurs.

This variegated copper ore ran a remarkable 70% copper as chalcocite and bornite had crystallized in the sandstone, where they formed thick veins and crystallined pockets. To give you some idea of how rich this Bristol ore was, today's copper mines run about 3% copper! The Bristol deposit also yielded silver in reasonable quantities.

However, there is a division between primary and secondary sulfide minerals in terms of semiconductor properties, collector type, and optimum flotation conditions. As the iron content in the copper sulfide mineral becomes reduced, from chalcopyrite to bornite to chalcocite, the lower Eh is preferred for flotation (Lotter et al., 2016).
