    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.
