Gold Flotation Mineral ProcessingMetallurgy

2020-6-17  Lime should not be used because it is a depressor of free gold and inhibits pyrite flotation. Sodium sulphide is often helpful in the flotation of partly oxidized sulphides but must be used with caution because of its depressing action on free gold. Copper sulphate is frequently helpful in accelerating the flotation of pyrite and arsenopyrite.

2020-6-2  Yes, this is difficult, partly due to the issue of gold being easily floatable and copper eating up a lot of cyanide. For the the simplest way at the process plant level it would generally be a combined flotation, followed by an ammonical (ammonia based) leach of the copper, and then cyanide for the copper, but this is far from easy.
