In contrast, the P266E feedwell has high levels of shear along the entire internal surface of the cylindrical section, as well as the external wall of the truncated inner cone. Based upon these shear rate profiles, the P266E feedwell would be expected to have the lowest scaling rate of these four feedwell designs.

High-rate thickeners also have a smaller tank volume, so less volume is required for storing the product if the tank has to be emptied. Because of this, high-rate thickeners can start up and shut down faster than conventional thickeners. However, due to their smaller size, high-rate thickeners require faster settling rates.

Operation of slurry thickeners is generally a compromise between clean overflow water and underflow density. Either the 22m tails thickener will achieve a high underflow density which enables maximum water and cyanide recovery. Or it operates to improve overflow water clarity enabling a positive impact on gravity gold recovery.
