  • Scale-up in froth flotation A state-of-the-art review

    Froth flotation works on the basis of surface chemistry fine mineral particles are separated according to their hydrophobicity. This separation process disperses small bubbles of gas generally air inside a flotation tank also referred to as flotation cell. The tank contains a mineral suspension in an aqueous media called the pulp.
