Abstract: A process for the flotation of copper minerals employing xanthates, wherein the copper minerals are strongly activated in at least one stage at a pH of 10 to 12 and then conditioned with a dispersing agent or a flocculating agent prior to flotation, the process showing marked improvement in grade and recovery in the case of refractory ores and ore containing talc and clay, and being effective to concentrate copper sulphides, copper silicates and copper oxide in the same circuit.
