ABSTRACT OF THE DISCLOSURE This invention relates to a process of regenerating and recovering lead from lead sulphate-containing wastes which comprises (i) contacting a lead sulphate-containing waste with an aqueous solution of an alkaline substance both capable of transforming said lead sulphate into a sparingly water-soluble or water- insoluble lead salt and capable of producing a readily water- soluble or water-soluble sulphate as by-product, (ii) subjecting to roast-reduction solid phase obtained by solid- liquid separation of the reaction product so formed to regenerate and recover lead and (iii) double decomposing liquid phase obtained by said solid-liquid separation to recover said alkaline substance in a form of an aqueous solution for reusing in said contact step of (i). The process of this invention is an improved process capable of regenerating and recovering high purity lead low in costs as well as to commercial advantage without trouble of waste gas disposal in excellent recovery from lead sulphate-containing wastes, such as battery scrap, smoke ash at the time of smelting lead and so on, by extremely simple means and operations.
