More recently it was reported that when using a dithiophosphate collector 90 of the copper sulphide minerals and 93 of carrollite could be recovered from mixed oxide sulphide ore at ambient ph in a laboratory batch flotation experimentfinal concentrate grades after the sulphide flotation stage were 122 cu and 038 co

Copper oxide ores are commonly difficulttofloat due to its molecular structure and adding sodium sulfide as activator is necessary however its dosage to the flotation pulp must be strictly controlled as it is also a powerful depressant for copper sulfide minerals and will if in excess depress the activated copper oxide minerals this depression will be alleviated while ammonium sulfate is added as it
It treats an ore which is a mixture of sulphide and oxide copper minerals in the flotation of mixed sulphide oxide ores the sulphide minerals are floated first then followed by a

From past reviews the recovery of copper from sulphide mineral using xanthate and pine oil is relatively easy but mixed oxidesulphide 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 simultaneously
