Foam fractionation Wikipedia

Foam fractionation is closely related to the allied process of froth flotation in which hydrophobic particles attach to the surface of bubbles which rise to form a pneumatic (i.e. rising) foam. In this way, relatively hydrophobic particles can be separated from relatively hydrophilic particles.
