flotation of gold ore

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
