    Sulfide Mineral - an overview | ScienceDirect Topics

    Sulfide minerals are floated using mostly xanthates, dithiophosphates, and other thio compounds as collectors. The mineral-collector interactions and the selectivity in separating individual sulfide minerals from each other and from the rest of the nonsulfide particles can be controlled by a careful adjustment of pH and oxidizing, reducing, and complexing additives.
