Froth Flotation Process - Mineral Processing & Metallurgy

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.
