Flotation cells require precise control of compressed air because the frothing process efficiency is based on the speed of the froth as it moves from the surface of the slurry to the recovery area. The speed of the froth is controlled by the air bubbles induced into the flotation cell, tank level and reagent dosages.

The tanks, known as flotation cells, are agitated this adds air, forming bubbles to which the hydrophobic minerals link. As a result, the minerals to rise to the top of the cell. There, they collect in a launder. The ore that does not float is taken away as tailings, which may be subjected to further flotation.

Froth flotation Froth flotation is a common method to extract a certain type of mineral from ore while depressing the amount of undesired minerals in the extracted concentrate. It is done by adding certain chemical reagents to selectively rendering the desired mineral hydrophobic. In a flotation cell, air bubbles then lifts the mineral.
