plate capacity. The flotation volume depends on the overall unit-averaged flotation rate, which is essentially the kinetic rate of the two-step process shown in Equation 1. If the rate of this reaction can be doubled, while achieving comparable enrichment and recovery, then the size of the flotation equipment can be reduced by half.

It is possible to increase the rise rate of the formed flotation aggregates, and thereby enhance the efficiency of flotation treatment via secondary saturation of the flotation cell with d b = 0.1-0.3 mm air bubbles. The air bubbles of 0.02-0.07 mm diameter float up in laminar flow regime but create light turbulence in the flotation cell.
