To answer your question I think it’s best to consider the anatomy of forced air vs. induced air (e.g. WEMCO)flotation cells. The induced airflotation cellhas the rotor position at the top of thecellas it needs to be close to the surface to pull in air; hence the majority of the mixing energy is dissipated in the top of thecell.

Concentrates of 70.2% iron assaying less than2% SiO2(1.3 to 2%) with recoveries which can reach 95% were obtained in a pilot circuit in which flotation was combined with magnetic separation and screening of the +44 micrometres fraction. A mixed magnetite-hematite ore …

It is noteworthy to point out that in Anshan, China, magnetic separation is often used in combination withreverse anionic/cationic flotationto upgrade low grade iron ore from ~29% Fe to ~50% Fe before flotation. Such a configuration has the advantage of removing some of the slimes in the magnetic separation stage.
Flotation, in mineral processing, method used toseparateandconcentrate oresby altering their surfaces to a hydrophobic or hydrophilic condition—that is, the surfaces are either repelled or attracted by water. Theflotation processwas developed on a commercial scale early in the 20th century to
Imhof et al. (2005) detailed the use of pneumatic flotation cells to treat a magnetic separation stream of a magnetite ore by reverse flotation to reduce the silica content of the concentrate to below 1.5%. From laboratory testing, they claimed that the pneumatic cells performed better than either conventional mechanical cells or column cells.

Direct shipping of high gradeiron ore, because of depletion or partial depletion of reserves, or high costs of operation has forced operators to use some means of beneficiation to produce an acceptable product with the lower gradeiron orereserves. Deposits of comparatively lower gradeiron orethat remain relatively untouched or by-passed, are now most important because of increase in ...

FlotationFroth an overview ScienceDirect Topics. The frothflotationtechnique was originally developed in about 1910 to raise the copper concentrations of the stripmined ores of Bingham Canyon, near Salt Lake City [9], and was further perfected for the differentialseparationof lead, zinc, andironsulfides at Trail, B.C., at about the same time [10].
