<p>A process for the recovery of gold from anion exchange resins, the method comprising eluting with a nitrate salt to displace gold from the resin. The gold has been loaded on to the resin from a thiosulphate leach solution or pulp. The nitrate salt is preferably provided in the form of ammonium nitrat e. Also provided is a process for the recovery of gold from thiosulphate leach solution or pulp, the method comprising the method steps of loading gold fro m a thiosulphate leach solution on to an anion exchange resin, eluting with a nitrate salt to displace gold from the resin, and recovering thiosulphate fr om the leach solution using a resin.</p> |
