- Best Mesh Size For Copper Froth 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.

Froth flotation was commercially introduced early in the 20th century. Now, almost 100 years later, it is the most important and widely used separating method for minerals.In its application to mineral flotation, the ore is first ground in water to a certain size to produce a suspension which is then subjected to vigorous mixing in a suitable vessel.
