Abstract
A feedwell comprising a plurality of holes disposed in a bottom thereof, at least some of the holes having a tube disposed thereabout which extends downward or otherwise away from an interior of the feedwell. Optionally, a large center hole can be provided and it can have a tube disposed around it. By providing a plurality of holes spread across a large portion of the bottom of the feedwell, lower velocity flow rates from the feedwell to a sedimentation chamber can be provided, thus reducing induced turbulence in the fluid within the sedimentation chamber, while still providing sufficient separation of the feedwell from the sedimentation chamber so that the contents of the feedwell can be properly and adequately mixed.
