Froth transport is essential to recover concentrates into launders and froth mobility may be adjusted by chemical additions, the use of paddles and/or booster cones as in the Outokumpu HG technology. The reduction of the distance that the flotation froth must travel can be achieved by the inclusion of launders across the surface area of the cell.

The choice of depth must consider climate and wastewater temperature. The improved performance that could result from increased depth may be lost if the extra hydraulic detention time provided by the additional depth creates septic conditions (i.e., biological activity), which, in turn, results in floating sludge.

A column flotation system including tailings recirculation. The system includes a column for particle separation and a gas injected reactor providing the site for bubble generation within a treated slurry feed. The reactor may contain a plurality of the spaced internal discs that cause shearing of the slurry to generate and entrain bubbles therein.

This method of froth floatation is a method of mineral processing in which different minerals are separated selectively. Such ores containing multiple metals such as lead, copper and zinc can be selectively extracted by using froth floatation. The minerals that do not float into the froth are called the flotation tailings or flotation tails.

When using vacuum filters, the column cells reduced the ash content of the froth product to 6.1% (Case C1), compared to 8.9% for conventional flotation (Case B1). This reduction allowed the 1.50 × 1.58 RD middlings to be recovered, so that 34 t/h (916 - 882 = 34 t/h) more production could be realized compared to the conventional circuit.
