This research presents three models of froth flotation that recognize flotation as an interfacial phenomenon wherein the rate of solidssurfacearea removal is related to the bubblesurfacearea flux. These models use two "streams", air and liquid, within the vessel. The solids within the column are associated with one, or both, of these streams.

Principle Of Operation Froth flotation starts by crushing and grinding, of the ore for processing and break the rocks into the wanted mineral and the useless material,this is known as liberation. The ore is ground into a fine powder and mixed with water and oil .The desired mineral is made hydrophobic by the addition of a collector chemical.
water into the froth and hence be less selective due to increased entrainment.
