Scaleup in froth flotation: A stateoftheart 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.

Flotation Machine an overview | ScienceDirect Topics

Froth flotation depends on differences in surface properties between coal and shale. Air bubbles are generated within an aqueous suspension of fine raw coal with a solids concentration of less than 10%. The hydrophobic coal particles attach to the air bubbles and are buoyed to the top of the froth flotation cell where they are removed as froth.
