FIELD: automotive industry; chemical industry; methods of reprocessing of the spent lead storage batteries. ^ SUBSTANCE: the invention is pertaining to the reprocessing of the spent lead storage batteries. The method provides for simultaneous dissolution of the non-destructed leaden plates with the active mass in the electrolyte and the electrochemical extraction of the lead. As the electrolyte use the solution of sodium hydrotartrate and the sodium hydroxide, and the electrochemical extraction of lead conduct at the current density of 5-15 mA/cm2. The process is ecologically pure, the used electrolyte is harmless, it contains the insoluble antimony, the passivation of the anodes in it is minimal, the practically complete utilization of the lead from the spent lead storage batteries is reached. ^ EFFECT: the invention ensures, that the described method is ecologically pure, the used electrolyte is harmless, it contains the insoluble antimony, the passivation of the anodes in it is minimal, the practically complete utilization of the lead from the spent lead storage batteries is reached. ^ 1 tbl, 3 ex |
