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.
