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.

The Froth Flotation Process is about taking advantage of the natural hydrophobicity of liberated (well ground) minerals/metals and making/playing on making them hydrophobic (water-repel) individually to carefully separate them from one another and the slurry they are in. For this purpose we use chemicals/reagents: Frothers (MIBC) is …

Froth flotation is a widely used physicochemical separation technique that exploits differences in the wettability of mineral/particle surfaces to selectively separate hydrophobic from hydrophilic materials. The process involves chemical treatment of a pulp to create conditions favorable for the attachment of particles to air bubbles.
