12.3: flotation properties of individual copper

In some cases, chalcopyrite is also present with bornite and covellite. Chalcopyrite from coarse-grained sulfide ores floats readily with xanthate collector in a pH region 5 11.5. Chalcopyrite, without any impurities present in the crystal structure, is a stable mineral and does not oxidize readily

Apr 01, 2014 · It is well known that chalcopyrite can be recovered by flotation in the absence of collectors under oxidizing conditions, but not under reducing conditions (Heyes and Trahar, 1977). This is because mild oxidation results in the formation of a hydrophobic sulfur-rich surface, due to the dissolution of iron ions ( Gardner and Woods, 1979
