Reagents for the removal of iron minerals include a combination such as hydrofluoric acid for a pH of 5, sodium resinate and a frother. The conditioned pulp is then diluted to a 20-25% solids for flotation. Complete removal of iron minerals along with some remaining feldspar is accomplished in a froth product which is small and is discarded.

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.
