The anode dissolution of ternary Pb-Ag-Bi metallic alloys with different components concentration has been studied in the molten KCl-PbCl₂ eutectics. A lead dissolution was found to be the main process in the Pb-Ag-Bi (60.0–15.0–25.0), Pb-Ag-Bi (42.9–21.4–35.7), Pb-Ag-Bi (7.0–34.9–58.1) alloys within the whole interval of studied anode current densities. The Pb-Ag-Bi ((4.8–35.7–59.5) and Pb-Ag-Bi ((2.4–36.6–61.0) alloys at the anode current densities of 2.3 A/cm² and 0.14 A/cm² have the limiting diffusion current of lead dissolution. At the anode current densities exceeding the aforesaid values a bismuth dissolution takes place. The number of electrons participating in each electrode reaction is determined for each mechanism of metal electrodissolution. A regime of electrochemical separation of lead alloys is chosen based on the analysis of polarization curves. Metallic lead and Ag-Bi-Pb (5.1 wt%) alloy were obtained in the laboratory electrolytic cell.
