Copper ores

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...

copper ore concentrations

The process of extracting copper from copper ore varies according to the type of ore and the desired purity of the final product Each process consists of several steps in which unwanted materials are physically or chemically removed, and the concentration of copper is progressively increased...
