FIELD: metallurgy.
SUBSTANCE: method includes electrolytic refining of lead in the melt of salt halogenides with use of liquid metal cathode and anode. At the same time the process of electrolysis is carried out with application of one and more bipolar electrode, such as liquid lead, at cathode density of current from 0.5 to 2.0 A/cm2, anode - from 0.3 to 1.5 A/cm2 and temperature of 450-600°C.
EFFECT: higher extent of raw lead treatment from admixtures.
