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 …

The effect of particle size distribution on froth stability in flotation

Many tests have been carried out using static froth column experimental systems to measure froth stability (e.g. [8], [30], [4]), however there are few reported studies into particle size effects on froth stability for a flowing flotation froth. This is due, in part, to the difficulty in decoupling particle size and liberation effects.
