Flotation Copper Collectorless

Flotation Copper Collectorless

2005-5-10The collectorless flotation of chalcopyrite requires that the flotation occurs in a neutral or slightly oxidising environment. Previous studies have shown that freshly fractured flotation of chalcopyrite increased when the redox potential Eh was in the neutral or slightly oxidising region.

    The interaction of OM with sulphide minerals and its effects on their flotation are little understood. Although chalcopyrite recovery and grade are generally high in the flotation of most copper and molybdenum ores, this is not the case for molybdenite, whose flotation is much lower and sensitive to changes in hydrodynamic and pulp conditions in the flotation cell 9,10,11,12.

    Reduction of copperII to copperI and the formation of new copper sulphide phases are responsible for the activation of pyrite flotation by Cu2. This is an electrochemical process. However, adsorption of lead hydroxide on pyrite surface is principally responsible for the activation of pyrite flotation by Pb2.
