Flotation is a process in Liquid Solid Separation technology whereby solids in suspension are recovered by their attachment to gas usually air bubbles, usually with objective of removing the solids from the liquid. The particles most effectively removed are in the size range from 10 to 200 μm. The particle bubble aggregates that are formed have a density less than the suspension itself

Collectors and modifiers give selective flotation of copper minerals from non Cu minerals. Foams keep Cu minerals floating at the top of the cell. the addition of branched chain alcohols and alcohol mixtures creates stronger foams which however, break down quickly when they overflow the cell. Foams stabilize the foam by absorbing their OH polar end into the water. Foam should not have a long
