Abstract
A flotation separation system for partitioning a slurry comprises a flotation separation cell that comprises a sparger unit and a separation tank. The sparger unit comprises a slurry inlet for receiving a slurry and a gas inlet for introducing a gas into the slurry. The sparging mechanism disperses the gas bubbles within the slurry. A high shear element comprising a rotating shaft and a rotating high shear element mounted to it located within the sparging mechanism shears the gas into a bubble dispersion within the slurry. A slurry outlet discharges the slurry containing the bubble dispersion into the separation tank. An adjustable distributor plate at the slurry outlet restricts the flow of slurry through the slurry outlet. The distributor plate is mounted to the rotating shaft and rotates with the high shear element.
