Copper ores. The main copper sulphide minerals are chalcopyrite chalcocite , covellite , bornite , tetrahedrite 12Sb4S13) and enargite . The largest source of copper is from porphyry ore deposits in which one or a combination of the aforementioned minerals occurs.
The main ore mineral of copper in Australia is chalcopyrite . Bornite , covellite and chalcocite are also important sources around the world and, in addition, many ore bodies contain some malachite 2 ), azurite 2 .Cu 2 ), cuprite , tenorite and native copper.
Copper minerals and ores are found in both igneous and sedimentary rocks. Mining of copper ...
Porphyry copper ore is challenging X ray mineralogy. The mineralogy of the ore, concentrates and residues is complex. Twenty or more minerals are to be quantified in most of the samples. Peak overlap is massive and may mask minor phases. Clays and other layered material make a reproducible sample preparation difficult. From Mine to Metal
