PCT No. PCT/AU84/00058 Sec. 371 Date Dec. 7, 1984 Sec. 102(e) Date Dec. 7, 1984 PCT Filed Apr. 12, 1984 PCT Pub. No. WO84/04058 PCT Pub. Date Oct. 25, 1984.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. The overlying depletion layer is diverted outwardly from inner wall (15) 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 as diverting the overlying depletion band towards outer wall (13). The water which has become separated from the slurry due to centrifugal force can be rehomogenized with the remaining concentrate by restricted passage between deflector means (22,26).
