Özet

The aim of this work is to investigate the effect of some operating variables and particle size on the Jameson cell performance. This is done by investigating the effect of varying different parameters such as concentrate flow rate and immersion depth of the downcomer for separation tank recovery, while jet length, jet velocity and holdup within the downcomer are used for downcomer recovery. It was found that altering these parameters play a significant role in recovery of different sized particles. An increase in concentrate flow rate and a decrease in immersion depth result in much more improving effect on recovery as particle size increases. An increase in jet length, jet velocity and holdup results in the recovery improvement for fine particles and loss of recovery for medium/coarse particles. (c) 2007 Elsevier Ltd. All rights reserved.
