Abstract
A flotation separation system is provided for partitioning a slurry that includes a hydrophobic species which can adhere to gas bubbles formed in the slurry. The flotation separation system comprises a flotation separation cell that includes a sparger unit and a separation tank. The sparger unit has a slurry inlet for receiving slurry and a gas inlet to receive gas with at least enough pressure to allow bubbles to form in the slurry within the sparger unit. The sparger unit includes a sparging mechanism constructed to disperse gas bubbles within the slurry. The sparging mechanism sparges the gas bubbles to form a bubble dispersion so as to cause adhesion of the hydrophobic species to the gas bubbles substantially within the sparger unit while causing a pressure drop of about 10 psig or less across the sparging mechanism. The sparger unit includes a slurry outlet to discharge the slurry and the bubble dispersion into the separation tank.
