To achieve separation, an air sparging device is required to produce bubbles in the flotation cell. In column flotation operations sparging devices generate small bubbles into the cell to carry the desired mineral to the surface for later recovery and processing. However, field studies suggest that air injector systems are not always optimized.

Air Agitation Sparging Systems for Electroplating Applications The preferred air supply (blower) for air agitation of electroplating solutions is of the "Roots" high volume, low-pressure type. The blower selected should be installed with the necessary in-line oil and water separation traps to ensure an oil free air supply.
Unlike conventional flotation cells, columns do not use mechanical agitation. Feed slurry enters the column in the upper third of the body, and descends against a rising swarm of fine bubbles generated by an air-sparging system. Targeted particles collide with, and attach to, the bubbles, and rise to the top of the column.
