Abstract
Acid-leach residue resulting from the sulphate roasting of Zn-Pb Egyptial carbonate ore is used for the production of
lead, after hydrometallurgical treatments. Studies to investigate various baths for the deposition of lead and lead
dioxide have been carried out. The results showed a wide variety of electrolysis, either soluble simple salts, or those
containing complex anions and in virtually all cases, very high current efficiencies are obtained. The effects of various
factors on the electrodeposition of Pb and PbO2 are discussed. In commercial practice, the properties and service
requirements dictate the precise electrolyte that should be used since the properties of electrodeposited lead vary
with the baths. Mechanism of the electrolytic production of the element and its dioxide is discussed. The results
spectrophotometric and chemical analyses revealed that the purity of the metal is > 99%.
