The invention relates to a flotation machine for flotating minerals and the like from slurries containing these particles. In the flotation machine of the invention, above the feed opening (15) of the flotation cell there is formed a froth bed (11) which is adjustable in volume and/or surface area. The regulating and washing members (10, 13) of the froth bed are arranged within the froth bed ...
The other school of mind deals with the coarse particle processes mainly owing to the low energy needs, that includes flash, fluidized bed and HydroFloatTM cells. The third and newest system proposes processing both fine and coarse sizes by flotation machines like oscillating grid flotation (OGC) and Reflux flotation cells.
