An improved process for refining lead bullion containing antimony, in which the bullion is initially heated in a refining vessel to about 25° F. (14° C.) above the bullion melting point, and is thereafter kept molten primarily by exothermic process reactions. The process includes the steps of melting the leadantimony bullion, agitating the bullion, adding caustic soda and metallic sodium to ...
