Column Flotation Cells
Column flotation cells, like mechanical cells, are used to perform mineral separations. Column cells do not use mechanical agitation (impellers). Instead, mixing is achieved by the turbulence provided by the rising bubbles. Columns are mostly used to produce final grade concentrates because they are capable of high selectivity.
A novel scale-up approach for mechanical flotation cells
Finally, for flotation bank design, the use of a methodology consisting of the sequential calculation of each individual cell is recommended (Yianatos et al., 2008c). For this purpose, the dimensionless factors α, β and γ, accounting for the froth, mixing and segregation effects, must be estimated for each cell downstream from the flotation ...

Flotation cells: Selecting the correct concentrate launder design
As with the internal peripheral launder the froth is pushed to the launder by the froth crowder. This design, however, provides more froth surface area. The external peripheral launder does not consume cell volume, so the effective cell volume for flotation is also higher. This launder is predominantly used on smaller TankCells.
