Copper-bearing minerals are not only numerous, but widely though irregularly distributed. More than this, copper is found associated with many different metals and under varied conditions. Nevertheless but few copper-bearing minerals are important in the ores of this metal, and the number of important producing districts is comparatively small. ...

In order to recover copper from extensive low-grade ore deposits, new and more efficient processing methods were developed around the turn of the century. Those processes made possible the economic use of large porphyry ore deposits - one in which the copper-bearing minerals are widely dispersed throughout the host rock.

Copper (Cu) ore is a naturally occurring mineral deposit that contains copper in varying concentrations. It is an important industrial metal that has been used by human civilizations for thousands of years due to its excellent electrical and thermal conductivity, high ductility, and resistance to corrosion. Copper is widely used in various applications, including …

Copper is found in many minerals that occur in deposits large enough to mine. These include: azurite, malachite, chalcocite, chalcopyrite and bornite. Most copper comes from chalcopyrite. The world's leading producer of copper is Chile, followed by the Congo, Peru, China and the US. The majority of copper in the U.S. is produced in Arizona.

The elevated oxygen levels facilitated the diagenetic processes that converted copper-bearing labile minerals to amorphous iron-oxides and smectite and then in turn to hematite and illite. When oxidized brines flushed through the basin successions, the liberated copper was transported to units containing carbon-rich mudstone and the metals were ...

In historically high-grade deposits, it is economical to only recover chalcopyrite—the primary copper-bearing mineral in porphyry copper ores—and ignore minor copper-bearing minerals with high arsenic and/or antimony impurities (e.g., enargite, Luzonite and tennantite). With low-grade deposits, however, even enargite, Luzonite and/or ...

Carrollite is the dominant cobalt-bearing mineral, while there are four copper-bearing sulphide minerals: bornite, chalcopyrite, chalcocite and again carrollite. As these minerals make up 42 % of the feed sample, it can be stated that this sample is sulphide rich. The main gangue minerals are (Fe) dolomite, quartz and magnesiochlorite.
