Kell is a hydrometallurgical treatment option for the recovery of platinum group metals (PGMs), gold, silver, and base metals from flotation concentrates to refined products on site. The process is cyanide-free, while eliminating emissions of sulphur dioxide, arsenic xide, and other toxic species often emitted by smelters and roasters.

The key to the gold flotation process is adjusting the flotation conditions so that gold particles can combine with air bubbles and float, while other minerals do not. In practical application, optimizing and adjusting the process according to the specific situation is necessary to obtain the best gold recovery rate and quality. 1.
