METHOD OF RECOVERING GOLD AND METHOD OF MANUFACTURING GOLD USING THE SAME

摘要

Gold included in metal sulfide ore is efficiently recovered at low cost. The method of recovering gold comprises leaching gold using acidic leachate which includes chloride ions and/or bromide ions as anions and copper and iron as cations from gold-bearing sulfide ore to the acidic leachate onto heating; adsorbing the gold in the acidic leachate by activated carbon; and eluting the gold adsorbed on the activated carbon with an alkali solution to obtain a concentrated gold solution.
