Effect Of Reagent Chemistry On Flotation Of Mixed Copper

From past reviews, the recovery of copper from sulphide mineral using xanthate and pine oil is relatively easy, but mixed oxide-sulphide minerals do not respond to traditional sulphide collector. There is no common reagent to recover copper from both oxide and sulphide mineral, which is a great challenge in flotation of both the minerals ...
