The effect of particle size distribution on froth

Aug 31, 2017· Many tests have been carried out using static froth column experimental systems to measure froth stability (e.g. , , ), 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.
