<p>In wet gravity separation of solids according to specific gravity an outer depleted band partly overlies an inner concentrate band limiting yield and/or purity of separated concentrate. According to the invention the overlying depletion layer is diverted outwardly from inner wall 11 relative to the concentrate band. Deflection means (20) cause a bow wave in descending slurry which fans out the concentrate aiding precise setting of downstream splitter blade (18) as well a diverting the overlying depletion band towards outer wall (13). In preferred embodiment water which has become separated from the slurry due to centrifugal force is re-homogenized with slurry by restricted passage between deflector means (22,26).</p> |
