Woodgrove Technologies developed the flotation cell called Staged Flotation Reactor (SFR). David mentioned the main features of the SFR cells. There are other similar flotation cells, but they have some operating and technical problems (e.g. sanding, circulating load is not handled properly, the residence time, etc).

One of the alternative but effective flotation techniques, mainly on a smaller scale, is electroflotation, or perhaps it should be correctly called electrolytic flotation, owing its name to the bubble generation method it uses (i.e., electrolysis of the aqueous medium); certain advantages of this technique have been stressed . The used cell ...
