assessment, pilot testing, design, and operation of air sparging systems has remained largely empirical, with variability in approaches by different practitioners Bruell et al., 1997 Johnson et al., 1993 Johnson
Column flotation which employs a counter-current flow of slurry and air bubbles has proved to be a better alternative to the conventional mechanical cells for separation of minerals. Because of the distinct advantages of column flotation over mechanical cells, it is gaining wider acceptance in industry.

versely, in mineral flotation or dispersed air flotation systems, about 10 m3 of air are dispersed into 1 m3 of water pulp or 500 times more than that used in DAF. Thus, DAF microbubbles are used to capture only the small, light solids and metal-ion hydroxide flocs, bacteria, etc., having specific weights close to that of water.
