摘要
Gold included in metal sulfide can be efficiently adsorbedon activated carbon and gold and silver adsorbed on theactivated carbon can be efficiently eluted. The method ofeluting gold and silver comprises:leaching gold and silver using acidic leachate whichincludes chloride ions and/or bromide ions as anions andcopper and iron as cations from sulfide ore bearing goldand silver to the acidic leachate by heating;adsorbing at least the gold and silver in the acidicleachate on activated carbon; andeluting gold and silver on activated carbon, on whichat least the gold and silver are adsorbed, by using anaqueous thiosulfate solution that is maintained at lessthan pH 7.
