Flotation Depressants
First let's change the amount of the Flotation Depressants used. The valuable mineral that isn't liberated from the unwanted mineral will begin to be depressed along with the waste. 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.

A significant review of froth stability in mineral flotation
Flotation was first performed in 1860 (Arbiter, 2000) and is a technology that utilizes the differences in physicochemical properties of various mineral surfaces to achieve specific separation (Wills and Munn, 2005), as depicted in Fig. 1.This process involves hydrophobic particles adhering to air bubbles being transported to the froth layer, whereas hydrophilic …
