In principle, the cell functions as a shallow flotation cell. As the air and pulp are hydrau-lically lifted to the top of the pulp recircula-tion well, the mineral laden air bubble has only to travel a short distance on its own to the froth overflow level.

Froth Washing in Flotation | Encyclopedia MDPI
Column flotation cells are common in coal flotation or applications where a deeper froth is required . Wash water is also sometimes applied in mechanical flotation cells, although this is not very common; however, the water requirement is lower, mainly because these cells are operated at a lower froth height compared to column flotation cells.

Cytec Handbook. Capacity. Floating time of the ore is one of the determining factors in figuring the capacity. If an ore is slow floating and requires twelve minutes treatment time, and another ore is fast floating and requires but six minutes treatment, it is evident that a machine of only half the capacity is necessary in the last instance.
