For example, Clinger and McGregor (1987) carried out an extensive survey of flotation column installations. They compiled data on the volume ratios employed where flotation columns replaced mechanical cells. The flotation column to mechanical cell volume ratios encountered varied from 0.4:1 to 1.54:1 with an average value of 0.98:1.
