In the flotation cell an agitated slurry is aerated by introducing a cloud of air bubbles that are typically about a millimeter in size. The agitation of the slurry is sufficient to keep the solid particles in suspension although the suspension is usually not uniform with the larger heavier particles tending to remain in the lower parts of the ...
