12.14 Flotation Cell and Gas Dispersion Characterization
Improvements in flotation cell operation require parameters that can be measured and are related to the recovery and separation processes. The initial work adapted the approach taken to characterize mixers, leading to a series of scale-up criteria. Later work focused on the properties of the air dispersed into bubbles. Both approaches are briefly reviewed.
12.14.1 Mechanical Cell Scale-Up Parameters
Partly based on fluid mixing and gas–liquid reactor design in chemical engineering (Oldshue, 1983), several scale-up ...
