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

In the froth flotation process, the bubble is not only the selective interface of all kinds of mineral deposits, but also the carriers and vehicles of hydrophobic intentional mineral deposits, so it is necessary for the flotation machine to inhale (or press in) sufficient air, And can be fully dispersed in the pulp into a large number of moderately sized and evenly distributed bubbles in order .
