| titleOfInvention | Method for producing gold from copper electrolytic slime |
| abstract | PROBLEM TO BE SOLVED: To provide a method for producing gold capable of suppressing the precipitation of gold from an organic phase or an aqueous phase after solid-liquid separation. SOLUTION: Gold is extracted from an exudate of copper electrolysis slime containing gold with an organic solvent typified by DBC, and a halide concentration of the obtained gold-containing organic phase is added by, for example, sodium chloride. A method for producing gold in which gold is precipitated by reducing the gold-containing organic phase after being increased, and the silver-chloride electrode is preferably cooled to 25 to 50 ° C. with respect to the treatment solution after the reduction treatment An oxidizing agent such as sodium chlorite is added until the oxidation-reduction potential of the aqueous phase with the reference electrode becomes 800 mV or more and 1000 mV or less.
