The efficiency of a flotation cell is related to the return in aeration and sand suspension per unit of power expended. No general relationship is known between the flotation result on the one hand and a measure of either aeration or sand suspension on the other. Moreover, increased aeration and sand suspension are useful only to the extent ...
