Abstract

Disclosed is a method for recovering lead from a scrap which contains lead oxide, lead sulfate and antimony in an oxidized state. The method comprises the steps of: (a) continuously charging a refractory lined reaction vessel with the scrap together with a reductant effective for reducing lead oxide; (b) melting and agitating the charged material by means of a submerged lance at a temperature of from about 900.degree. C. to about 1150.degree. C. whereby some lead oxide of the scrap is reduced to form molten lead; (c) forming a slag layer above the molten lead produced in step (b); (d) maintaining an amount of lead oxide in the slag layer; (e) removing the molten lead, the removed lead having less than 0.5% by weight of antimony; and (f) concentrating as oxide in the slag layer the antimony oxide in the scrap.
