Abstract

189,013. Harris, H. Jan. 18, 1922. Dry processes of refining lead.-Oxidizable impurities, such as arsenic, antimony, tin, and zinc, are removed from lead by bringing the molten lead into contact with an oxidizing agent such as alkali nitrate, nitrite, chlorate, or hypochlorite, or a peroxide, in suspension or solution in molten caustic alkali, or caustic alkali and a fusible chloride. The molten metal is preferably passed through the reagent by means of the apparatus described in Specification 142,398 or 184,639. The temperature and the proportion of oxidizing agent may be so adjusted that different impurities are removed in succession.
