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.

Mechanical flotation machines, also known as conventional flotation machines, are the most common type used in industry. They consist of a series of cells arranged in a row, with each cell containing an impeller-driven rotor that rotates to create turbulence and disperse air bubbles into the slurry.
