It was found that biotite can be divided into copper bearing biotite and copper free biotite. Some copper bearing biotite existed in the form of monomer, and others aggregated with copper
احصل على السعرIn Victoria, copper bearing ores have been discovered in a variety of geological environments. These include deposits of exhalative volcanogenic origin, sulphide–quartz lodes in Ordovician sedimentary rocks, deposits associated with dykes and granites, and concentrations in chemically reduced Carboniferous sedimentary rocks.
احصل على السعرThe 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

احصل على السعرCopper is separated from the cobalt in the bulk concentrate by raising the pH up to at least 11 which depresses the cobalt minerals. Cobalt depression can be enhanced by small cyanide dosages. If the cobalt is found with chalcopyrite, bulk flotation can be carried out with xanthate at pH 10, and separation made at pH 4 with an amine and combinations of fatty acid to recover the cobalt minerals.
