Abstract

See full text

The present invention concerns a process for the recovery of lead from a lead pastel electrolytically, where the pastel contains lead sulfate. The process provides for the leaching of the non-desulfurised pastel and the subsequent removal of the sulfates by precipitation; the leachate containing the lead ions is then subjected to electrolysis for the recovery of metal lead. The present invention further relates to a process for the recovery of lead accumulator components, wherein the lead contained in the pastel of the accumulators is recovered according to the aforesaid process.
