Abstract

This study evaluated and optimised the activated carbon adsorption (ACA) process for the recovery of metals from alkaline glycine leachates. The use of activated carbon for metals adsorption remains industry’s preferred choice for the recovery of precious metals, from dilute solutions. The adsorption behaviour of metal glycine complexes on activated carbon, which was studied through the use of isotherms and kinetics, confirmed that ACA can efficiently recover gold over copper from dilute glycine solutions.
