05 mechanical flotation machines are divided into agitation cells which receive air from blower or “self-aerating” machines which use the depression created by the impeller to induce air. Both types are characterised by a mechanically driven high-speed impeller which agitates the pulp and disperses fine air bubbles into it.

Residence time distribution in large industrial flotation cells - Ipen

modelling the mixing conditions in a flotation bank of mechanical cells (3, 5 or 7 cells in series) can be well described as a series of N continuous perfectly mixed reactors, where N corresponds to the actual number of cells in the bank.
