FIELD: non-ferrous metallurgy. SUBSTANCE: method for refining of lead against antimony involves melting lead followed by reduction of lead in the melt of salts (namely, sodium carbonate and potassium carbonate). Mentioned above melting is carried out within 3-5 h at 415-425 C in the mixture of liquid sodium nitrate. Thus simultaneously pure lead and alloy are obtained; lead contains 0.02-00.4 % of antimony, said alloy contains 49.93-59.15 % of lead and 40.37-49.91 % of antimony. EFFECT: improves efficiency of the method. 5 cl, 1 tbl
