FIELD: lead metallurgy, possibly refining of black lead from impurities.
SUBSTANCE: method of electrolytic refining of lead comprises steps of anode dissolution and cathode reduction of lead in aqueous solution of electrolyte; using as electrolyte aqueous nitrate solution of salts of lead and sodium containing, g/l: lead (in the form of Pb(No3)2), 220 - 250; NaNO3, 180 - 200; HNO3- ,(1.5 -2)10-3 (pH =4,5); carrying out electrolysis at electric current density 450 - 480 A/m2, temperature 20 -25°C, electrolyte circulation rate 45 - 50 l/min.
EFFECT: improved efficiency of process, lowered exploitation expenses.
