    OPTIMIZATION OF AIR INJECTION SPARGERS FOR COLUMN

    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.
