  • Froth Flotation ProcessMineral 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 waterrepel 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.
