FIELD: metallurgy.
SUBSTANCE: invention refers to procedure of production of basic lead carbonate by electrolysis of water solution using anode lead containing material saturated with carbon dioxide. Also, electrolysis is carried out at cathode current density 25-30 mA/cm2, and pressure of carbon dioxide 0.5-0.8 MPa. As anode material there are used grids of spent lead accumulator.
EFFECT: raised efficiency of procedure.
