Abstract

251,736. Marks, E. C. R., (American Smelting & Refining Co.). March 17, 1925. Dry processes of refining lead.-Crude lead containing antimony in substantial quantities, is refined by maintaining it in fusion in an oxidizing atmosphere, for instance in a reverberatory furnace, at 1200-1700‹ F. At first a skim of tin oxide forms and is removed; then a fume of antimony oxide is liberated and a skim of antimony and lead oxides forms and is removed as long as the fume is produced. By the time the fume is no longer escaping the antimony has been reduced to about 5-7 per cent and the further removal of antimony is effected in the usual manner by skimming until the desired minimum content of antimony is attained. The temperature of the bath is then reduced for instance to 950-1000‹ F. when copper is separated as a skim.
