methods seeking separation of one sulphide from another by flotation are of two classes viz 1 those in which a difference in flotability of the two minerals is created or enhanced by conscious control of one or more of the activating phenomena of the process and 2 those in which the chemical nature of one of the sulphides is changed with …
