    Abstract: A process for obtaining metallic lead from its compounds present in an end-of-life lead-acid battery through a direct solid-solid reaction with metallic zinc includes a) dry mixing of the mixture of lead compounds present in an end-of-life lead-acid battery with a metered quantity of metallic zinc powder; b) an addition to the mass, during mixing, of water and of an aqueous solution containing a substance capable of forming soluble zinc salts; c) a separation of the solid, essentially consisting of metallic lead, from the liquid phase in which the soluble zinc salt is present; and d) an electrolytic treatment of the resulting previously separated solution in order to recover metallic zinc suitable for reuse in the dry mixing treatment.
