Column flotation devices were reintroduced for mineral processing by Boutin and Wheeler in Canada in 1967, when wash water addition to the froth was used to eliminate entrainment of hydrophilic materials to the float product. By the late1980s column flotation had become a proven industrial technology in the mineral industry.

Froth flotation

Froth flotation

Flotation columns use air spargers to introduce air at the bottom of a tall column while introducing slurry above. The countercurrent motion of the slurry flowing down and the air flowing up provides mixing action.
