5565 gold flotation cell problems

A great deal of work has been reported on specific ores but such studies rarely distinguish between the flotation of native gold and other gold minerals Flotation of gold ores covers a broad field and it is a rather difficult subject to generalize on Most problems in gold ore flotation are not connected with floating metallic gold

For example it is often desirable to remove coarse liberated grains of gold using gravity techniques prior to flotation as these high density grains often report to the tailings due to the flotation cell kinetics Similarly excess milling of coarse gold may result in the smearing of the gold within the mill and subsequent losses
