ABSTRACT:
The invention relates to an apparatus and a method for thickening liquids carrying suspended particles, such as a slurry containing minerals. The thickening apparatus comprises a tank (2), a feedwell (4), which includes a chamber having an inlet for receiving feed slurry (9) and an outlet in fluid communication with the tank and means for distributing the material in the tank, at least one conduit (5) for feed slurry to deliver a feed slurry (9) into the feedwell, means for diluting the feed slurry, when at least one separate dilute liquid conduit (16, 19) is directed tangentially with respect to the feedwell (4) and at least one inflow aperture (15) is arranged tangentially with respect to the feedwell for recirculating the dilute liquid from the tank inside the feedwell in order to dilute the feed slurry.
