The other type of flotation cells is a column cell. Column cells are tall round tanks that use compressed air to create air bubbles via spargers or cavitation tubes. These cells are used to perform mineral separations. Column cells do not use mechanical agitation (impellers). Mixing is achieved by the turbulence provided by the rising bubbles.

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. Above are illustrations of three flotation cells. 14.2 m3 (500 cu.ft) cell 2.8 m3 (100 cu ...
