Flotation Depressants - Mineral Processing Metallurgy

Aug 12, 2015  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.
