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

flotation in mineral processing method used to separate and concentrate ores by altering their surfaces to a hydrophobic or hydrophilic condition—that is the surfaces are either repelled or attracted by water The flotation process was developed on a commercial scale early in the 20th century to remove very fine mineral particles that formerly had gone to waste in gravity concentration
