USE OF ELECTROCHEMICAL METHODS IN PRODUCTION OF SECONDARY LEAD

The proportion of secondary lead in the overall balance of its product ion is continuously increasing, attaining 50-60% in industrialized cou ntries. Recycling of the metal is one way of decreasing the role of th e raw material factor in the economy. The proportion of lead batteries in the balance of secondary lead-containing raw material Is no less t han 70-75%. Almost all of this raw material is processed by pyrometall urgical methods, which always involve some ecological danger. An alter native set of technological operations which include separation of lea d from the sulfate-oxide fraction by electrolysis of molten media or a queous solution is of interest. The published data and results of pers onal studies are summarized in the review.
