<p>Process for the selective recovery of copper from an aqueous metal containing solution in which (a) the solution at a pH of 7 or less is contacted with a chelate exchange resin to selectively remove a substantial proportion or all of the copper from the solution onto the resin. The chelate exchange resin is in the form of an amine substituted cyclic compound on a glycidyl methacrylate substrate. The selectively removed copper is subsequently separated from the resin by elution.</p> |
