Recovery of Copper from Cyanidation Tailing by Flotation ...
12%This work mainly focuses on the recovery of copper which mainly exists in the form of chalcopyrite in cyanide tailings. Cyanide ions can depress the flotation of chalcopyrite after coating with graphitic carbon on the surface. 16, 17 A slightly high concentration of cyanide ion can reduce chalcopyrite hydrophobicity in the presence of xanthate.
