The results showed that molybdenite and talc were layered minerals which exhibited similar surface wettability. H 2 O molecule had hardly effect with molybdenite or talc and H 2 O molecule prefers to stay with water rather than the minerals surfaces. The reason why talc interferes with the flotation molybdenite has been revealed.
