Elution In Gold Processing

Elution and Carbon Reactivation - Resource book

Elution is the next step in the process, whereby the adsorption of the gold cyanide complex onto carbon is reversed. Loaded carbon is removed from the CIL circuit and the gold stripped from the carbon using a number of treatment steps. The result is a solution of high gold concentration (pregnant eluate).
