Beschreibung
Zusammenfassung:	production, recovery or refining of metals by electrolytic process. SUBSTANCE: method comprises steps of using treated material preliminarily melt and cast to mold as anode; realizing electrochemical dilution and deposition on cathode admixture metals; extracting gold as anode slime; providing gold content in anode material in range (5-50)mass%; performing electrolysis process in aqueous solution of acid and(or) salt with anion NO3 or SO4 at concentration (100-250)g-ion/l and at anode electric current density (1200-2500)A/sq.m and bath voltage (5-12)V. EFFECT: simplified manufacturing process, high factors of extraction of highly purified gold. 5 cl, 1 tbl
