Abstract

Ion exchange resins composed of a polymeric matrix functionalized with a piperazine group are suitable for separating gold cyanide from aqueous medium containing gold cyanide complex and other metal cyanide complexes in a process wherein the gold cyanide complex is preferentially retained on the piperazine-functionalized ion exchange resin and can be eluted with thiourea or a mixture of NaOH in ethanol. The polymeric matrix is preferably based on a polystyrene copolymer or on a polymethacrylate copolymer and the piperazine group is preferably the 4-(2'-hydroxyethyl)piperazin-1-yl group.
