Flotation of phosphates from the fine feed (35 x 150 mesh) presents very few difficulties and recoveries in excess of 90% are commonly achieved using conventional mechanical cells. On the other hand, recovery of the coarse phosphate feed is much more difficult and flotation by itself normally yields recoveries of just 60% or even less.

Application of Hydrodynamics in Design of Flotation

Recovery and recycling of waste paper has become increasingly important with demand for paper products sharply growing. The flotation process is the predominant technology for the removal of inks from waste paper because of its advantages. Flotation cells may be very different in size and shape, but the key elements ensuring aeration, ink collection and bubble separation are always present.

Jul 01, 1996 QPEC's 'cell-to-cell' design allows for a great deal of 'slurry to air' contact in the impeller/diffuser region, and also provides much greater control over the air addition to the cell, which can be critical in the efficiency and performance of the actual flotation and also in the ability to suspend the solids within the cell to avoid sanding.

Oct 01, 2009 The cell is based on a standard column design but employs a novel agitation mechanism where a series of baffle plates are oscillated sinusoidally through the fluid. This type of agitation has been shown to produce a more evenly distributed shear rate in the cell and allows the effect of agitation on particle–bubble contacting to be decoupled from gas dispersion effects.
