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.

Introduction to Mineral Processing Chevron Phillips Chemical

Frothers are liquids that produce the froth or foam on which the flotation process depends. The froth resembles soap suds and provides the physical separation between the mineral(s) floated and the pulp containing the waste. The froth must be strong enough to support the weight of the mineral floated and yet not be tenacious and non-flowing.

Frothers and Flotation Froth: Mineral Processing and

Apr 26, 2007· Good flotation frothers have branched hydrocarbon radicals and form loosely packed gaseous films at the liquid/gas interface. Their hydrophile-lipophile properties must be properly balanced and for most good frothers the HLB values are close to 6. This allows them to co-operate actively with the adsorbed collector in the moment of particle-to-bubble attachment.

Selectivity and power of frothers in copper ore flotation

frothers was probably related to their low dose used in the upgrading process. On the other hand, the enhanced flotation performance with C 4 E 3, C 4 E 1 and C 1 P 3 frothers can be attributed to the more stable froth. Frothers which produce more stable foam/froth are also more efficient in reducing bubble size (Laskowski, 2004).
