DetailsThe roles of three major components of the Reflux Flotation Cell are introduced. ... A high-shear rate in the downcomer is created by directly feeding the slurry with a high flowrate (Sutherland et al., 2020). In the mixing zone, compressed air from the outer tube enters the inner tube of the downcomer through a sparger made of micro holes.
Detailsno flotation can occur. Contact between particles and bubbles can be accomplished in a flotation cell such as the one shown schematically in Figure 5. Figure 5: Simplified schematic of a conventional flotation cell. The rotor draws slurry through the stator and expels it to the sides, creating a suction that draws air down the shaft of the stator.

DetailsIn order for flotation cells to perform effectively, these requirements have to be met and thus optimal use of energy is critical to the process. The distribution of the energy dissipation rate within a flotation cell determines both the capture of ultrafine particles (high shear) and the detachment of coarse particles (low shear) (Jameson, 2013).

Gas introduced into the bottom of a cell and dispersed into a water in the form of very fine bubbles will rise to the top of that cell and carry with it suspended solids and entrained oil. ... The star rotor revolves at a high rate of speed and breaks the incoming ...
