PyriteGold Recovery in Copper Rougher Flotation Tailings

Froth flotation is a widely used separating technique for the recovery of Cu and Au in porphyry coppergold ores. In these ores, chalcopyrite and gold are the main valuable mineral/metal phases, with pyrite being the key sulphide gangue mineral. However, in these ores gold is mostly associated with pyrite rather than the copper minerals.
