Abstract

Se recupera plomo de una pasta de plomo de una bateria de plomo-acido en un proceso de recuperacion electroquimica de plomo continua. En aspectos especialmente preferentes, la pasta de plomo se procesa para eliminar los sulfatos residuales y la pasta de plomo asi tratada se somete a una etapa de tratamiento termico que elimina la humedad residual y reduce el dioxido de plomo a oxido de plomo. De manera ventajosa, tal pretratamiento evitara la acumulacion de dioxido de plomo y la dilucion del electrolito.
