More ores are treated using froth flotation cells than by any other single machines or process. Non-metallics as well as metallics now being commercially recovered include gold, silver, copper, lead, zinc, iron, manganese, nickel, cobalt, molybdenum, graphite, phosphate, fluorspar, barite, feldspar and coal. Recent flotation research …

Mechanical agitation flotation machines: These units contain an impeller that is mechanically operated to mix and distribute air into the slurry. This mechanical stirring encourages the float of minerals by fusing them with air bubbles. A part of the flotation cell of an inflatable flotation machine is inflated using an outside blower.

To use the Smoluchowski equation, we need an estimate of the number concentration N b of bubbles in the flotation cell, which is related to the gas holdup. Dahlke and Gomez (2005) showed that in a flotation machine operating in a typical range of the superficial gas velocity J g, the gas holdup e was directly proportional to J g.
