RECOVERY OF LEAD VALUES ABSTRACT Lead values may be recovered from lead bearing sources such as lead sulfide in improved purity. The improved purity is obtained by sub- jecting soluble lead halides formed by the halogenation of lead sulfide and brine leaching the chlorinated product prior to treatment with a reducing agent followed by filtration and further treatment with an oxidizing agent whereby impurities as represented by other metal values are removed.
