Method for recovering Gold comprising elute Gold adsorbed on Activated Carbon prepared by an eluent through the addition of thiosulfate to an acidic aqueous solution to obtain Concentrated acid Gold solution and Method for producing Metallic Gold;

摘要

Gold adsorbed by activated carbon is efficiently recovered at low cost. The method of recovering gold comprises eluting gold adsorbed by activated carbon with an eluent prepared by adding thiosulfate to an acidic aqueous solution to obtain an acidic concentrated gold solution.
