    2020-9-28 · 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.

    Spargers are an industry tool designed to deliver gas into a column flotation cell or leach tank to ensure that bubbles are dispersed evenly throughout the flotation cell or leach tank. Typically a column flotation cell can contain up to 20 spargers in order to help the reaction in the cell while up to 16 spargers can be used for a leach tank.
