Froth Flotation Process

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. Think of frother as soap in your bathtub. Collectors (5100, 3418, Xanthate) are used as the base to making metals hydrophobic (water repellent) and allows it to attached to air bubbles. Think of collectors wax (water-repellent) on car paint that allows the water pearl away.froth flotation CuSO4 is the “activator” used to make Zn (sphalerite) ready to be covered by Collector. In the eyes of the Collector, activated Zinc is Copper. Think of CuSO4 as epoxy primer on raw metal before you paint it. pH Modifiers (MBS , Lime) are used to intensify or reduce collector’s water-repellent effect on mineral surfaces. This allows Flotation Collectors to act selectively towards certain minerals. Think of pH as the temperature of ambient air at which paint is applied to metal. Some paint work (stick) best to metals (than
