The self-aspirating WEMCO flotation technology, whether incorporated into the original 1+1 flotation machine design or the newer-generation SmartCell ® flotation cell, combines ease of operation with improved metallurgical performance. The result is excellent particle recovery in a simple, proven induced-air design.
Despite the high economic impact of poor flotation cell performance, control of flotation cells is notoriously challenging for two main reasons: (1) cell control is complex with several colinear variables, and (2) closed-loop control lacks high-quality continuous measurements for key process variables such as concentrate composition (i.e ...
The ever-increasing size of mineral processing operations has lead to the development of ever-larger flotation cells, the largest of which now hold over 300m 3 of slurry.
The flotation process is a separation technique primarily used in mineral processing for the recovery of minerals (Wills and Finch, 2016), that also finds application in other industrial processes such as wastewater treatment and paper recycling (Saththasivam et al., 2016, Vashisth et al., 2011).Separation of mineral particles by flotation takes advantage of …
