Gold Extraction & Recovery Processes
The process let to recover fine gold which is difficult to be recovered by gravimetric devices, and the coarse gold can be recovered from gravimetric concentrates. Thus, the process is an alternative to amalgamation and cyanidation. The process can be employed in small or big scale. The short time in reactors, let to have lower capital cost.
