Here, nt m is the dimensionless mixing time. A value of nt m = 39 arises for a typical tank having D T = 3D, and H = D T. We can now use this information to predict the new mixing time if the value of impeller speed changes during scale-up. Remember this applies to one specific design of impeller and tank geometry during turbulent mixing.
The rest of the pulp enters the lower tank for re-separation. This step continues to process the unfloated pulp to maximize the recovery rate of minerals.
