Froth Flotation - an overview | ScienceDirect Topics

Froth flotation has been used in coal and mineral cleaning operation for a long time. It is based on the difference in densities of materials. Normally, air bubbles are forced into the tank using external aerators or agitators, these tiny bubbles attaches to the surface of algal cells and by buoyancy, the cells are risen up in the tank.
