Abstract

El plomo se recupera de la pasta de plomo de una batería de plomo y ácido en un proceso continuo y electroquímico de recuperación de plomo. En los aspectos especialmente preferidos la pasta de plomo se procesa para remover los sulfatos residuales, y la pasta de plomo tratada de esta manera se somete a una etapa de tratamiento térmico que remueve la humedad residual y reduce el dióxido de plomo a óxido de plomo. Favorablemente, este tratamiento previo evitará la acumulación de dióxido de plomo y la dilución del electrolito.
