Depletion of high-grade resources has necessitated the use of low-grade fines, which contain good amount of mineral values and also liberate in finer sizes. Froth flotation, a physico-chemical surface-based process, is the most established solution, both technologically and economically, compared to other alternatives for fines beneficiation. …

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 …
