Flotation columns are also practical, as their footprint is small and a proper height will allow for effective multi-stages separation ( Moon and Sirois, 1983 ), akin to the operation of a distillation column with counter-current flow of coal- carrying bubbles up and ash-laden water down.

What Are Column Flotation Cells?

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.
