摘要

FIELD: non-ferrous metallurgy; refining lead from admixtures. ^ SUBSTANCE: proposed method of refining lead from admixtures includes electrolysis of melt of potassium chlorides and lead by anode polarization; anode polarization of black lead is carried out at current density of 0.41-1.2 A/cm2 at temperature interval of 480-700°C. Concentration of KCl ranges from 30 to 50 mole/%. ^ EFFECT: high degree of refining lead from admixtures; reduced duration of process without expensive reagents. ^ 2 cl, 1 tbl
