Froth flotation is a physicochemical separation technique that exploits the difference in the surface wettability of mineral particles (Wills and Finch, 2016).From a heterogeneous mixture of solids, hydrophobic particles are made to attach to gas bubbles and subsequently carried to the froth phase and recovered as a froth product (typically the value …

Flotation Depressants

For the floatation operator, the change that will become most apparent is, that the color of the froth will begin to reflect more of the wanted mineral's color. This is because the froth is becoming purer as the unwanted mineral, the iron pyrite, is being cleaned off of the bubble.
