  • Hydrometallurgical method of producing metallic lead from materials containing oxides, particularly from the active material of accumulators
    Patent number: 5262020
    Abstract: In a method of producing metallic lead from a material including lead dioxide and/or metallic lead, including a step for dissolving the lead contained in the material and an electrolysis step for the cathodic deposition of the dissolved lead, the dissolving step is carried out with the use of an acid electrolyte in the presence of a redox couple which has a potential between its oxidised and reduced oxidation states such as to reduce the lead dioxide and/or oxidise the lead and which can be regenerated during the step for the electrochemical deposition of the dissolved lead. The method is used, in particular, for the production of lead from the active material of spent accumulators.
