Abstract
124,019. White, C. H. Feb. 14, 1918. Liquating; dry processes of recovering and refining metals and alloys.-Brass is recovered from foundry ash and the like remaining in crucibles &c. after the brass has been poured therefrom, by heating the ash to 1050-1250‹ C. and stirring or kneading the mass so long as the molten brass continues to collect. A flux such as borax, glass, or soda-ash may be used, and copper may be recovered from the resulting slag electrolytically. A reducing agent such as charcoal or boron-copper may be mixed with the ash.
