PyriteGold Recovery in Copper Rougher Flotation Tailings

PyriteGold Recovery in Copper Rougher Flotation Tailingson its flotation was studied in a typical copper ore. A twostage (Cu and pyrite) rougher flotation indicated that maximum Au recovery (95%) can only be achieved with pyrite flotation (recovery, 93%). A decrease in grind size of the flotation feed from 70 µm to 38 µm and without pyrite flotation stage

Flotation of Chalcopyrite and Molybdenite in the Presence ...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].
