Froth transfer between flotation stages requires either gravity flow or pumping. The characteristics of the froth depend to a large degree on the type of ore being treated, the fineness of the particles, the solids concentration, the amount of air in the froth, the type of reagents used and the froth 'brittleness'.

The other two mechanisms, non-selective mechanical entrainmcnl and dropback from the froth to the slurry depend critically on the properties of the frother and froth stability in mechanical cells. In flotation columns, these two other mechanisms are not so important since the froth stability in this latter case is mostly determined by wash water.

In froth flotation, the injection of air and its dispersion into bubbles in the slurry are essential considerations in affecting hydrodynamic conditions. Air flowrate, for example, is one important control and optimization variable in deciding flow patterns, and it is also a parameter affecting both gas dispersion and flotation performance.

Physical Model of Flotation. The first premise, based on visual observation, is that the froth volume or height above a float cell reaches a maximum very quickly and much faster than its removal. This is borne out in batch experiments where each increment of cumulated recovery continues to decline with time once the froth is established.
