flotation of mixed copper oxide and sulphide minerals

alkaline flotation of copper sulphide

Traditional sulphidisation flotation techniques, which are widely used on copper oxide ore, can not be used in sulphide/oxide blends for simultaneous sulphide and oxide copper flotation as the sulphidising reagent will suppress the flotation of sulphide minerals as shown within this case study.
