Abstract
A flotation separation cell is disclosed having a rotor-stator pump assembly wherein a rotor body comprises integrally formed hub, blade and top plate members. These members form a gas chamber in an upper sector of the rotor. The blades are curvilinear and of parabolic or vortex shape. A gas stream which is conveyed to the gas chamber is discharged from the gas chamber in a transverse direction and flows in gas pockets along surfaces of moving blades for dispersion in a slurry.
