Experimental Research on Lead Extraction from
Alkaline Solutions by Electrolysis

Abstract:

The hydrometallurgical processing technologies of the oxide-sulfate paste resulting from the dismantling accumulator batteries are still belonging to a research process (level- laboratory, pilot, functional mode), nowadays. Lead solubilization can be carried out in lead chloride solutions (with NaCl, CaCl2), in acidic solutions (acetic acid, nitric acid, hexafluosilicic acid) and in alkaline solutions (NaOH) or amines. Leaching with sodium hydroxide solutions represents the most recent lead recovery initiative. The method is considered interesting due to its environmental pollution control and to the processing of both the oxide sulfate paste and other secondary resources such as volatile powders resulted in the extractive metallurgy of lead from primary resources. The lead extraction from alkaline solution by electrolysis, can be achieved with current efficiency of over 98%. The following initial conditions represent the starting point: the lead concentration in the electrolyte supplied: 17-30 g/L Pb, the electrolysis time: 2 h and the distance between anode and cathode: 40 mm. Under these conditions a maximum current efficiency and minimum energy consumption were obtained for the following values of the parameters taken into account: the cathodic power density 600 Am-2; the NaOH solution concentration 6 M; the process temperature, 350 C. Keywords: lead recovery, battery, hydrometallurgy, electrolysis, alkaline solution
