These lead bearing/materials and. some car.-
bon occur in 'varyin proportions, depending on. themanner m which the smelting operation is carried out; Heretofore, such .Y lay-.products have `been utilized for the-prof duction of basic: leadisulphate by a direct 2f smelting operation in whichia large 'pro orf ,tion of theirleadcotentsis. reduce to metallic lead or they havebeensmelted under conditions which. -wll reduce their lead contents vto metallic lead with .little 'or noproduction of leadsulphate.

In the practical use ofmy invention, the Alead by-'products availablel are carefully analyzed and properlyv mixed `to Agive a mixed roductfofv approximately uniform composition, suitable' for treatment. The
