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 what allows the formation of air bubbles.

The hydrophobicity of the particles is thus minimise, and hence their floatability. The flotation limit may spread without loss of selectivity by using a collector with a longer hydrocarbon chain. In order to aim producing greater water- repulsion, rather than by increasing the concentration of a shorter chain collector.
