Introduction Froth flotation is a surface-chemistry based process of separation of fine solids that takes advantage of the differences in wettability at solid particle-surfaces. Solid surfaces are often naturally wettable by water and termed hydrophilic. A surface that is non-wettable is water repelling and termed hydrophobic.

the kinetics of bubble–particle interaction in the fine particle flotation. Sometimes, for simplicity, froth flotation is simply termed as flotation. Froth flotation essentially is an application of foams. The separation process is based on the surface properties such as wettability and surface charge of the components to be separated.

control of a flotation process are classified as follows: The tendency of the ore to have variable physical, metallurgical, and surface properties produces significant changes in a flotation circuit. The particle size range of the flotation feed can be substantial because of ore hardness changes and changes in the operation of the grinding circuit.

Flotation is based on chemical phenomena occurring at the interfaces, solid/water and air/water. Surface Chemistry principles have played a significant role in the development of flotation technology. Knowledge of aqueous solution chemistry and electrochemistry has added to our understanding of the reactions in flotation systems.

of the flotation cell. The recovery of the froth is accomplished by the natural mobility of the froth which causes it to flow over the weir and the recovery is sometimes assisted by mechanical paddles. Within this general macroscopic view of the flotation process as a whole, several distinct micro processes can be identified.
