ABSTRACT:
An apparatus and method of diluting a solid particle-containing slurry in conjunction with a sedimentation process. A slurry is introduced into the launder portion of a feedwell and flowed vertically downward through an eductor nozzle having its exit location placed below the liquid level of a volume of clarified liquor. The eductor nozzle is positioned adjacent a diluent inlet such that discharge of the slurry through the eductor nozzle creates a low pressure zone, drawing clarified liquor through the diluent inlet for mixing and dilution of the slurry. A flocculating reagent may additionally be introduced into the diluted slurry for producing a floc and expediting settling of the solid particles.
