Copper Sulphide Ore Reagents For Copper Flotation

Alkaline flotation of copper sulphide nkvf-regio20.froth flotation is widely used for the treatment of base metal sulphides, and relies on the differences in surface chemistry between valuable sulphide minerals and gangue minerals xian et al., 2015b, ejtemaei and nguyen, 2017.pyrite fes 2 and other sulphide minerals are closely associated with each other in most copper ores, and their
