Abstract: A process for refining brass and cuprous chloride includes contacting solid cuprous chloride with molten brass scrap which converts the zinc in the brass scrap to a zinc chloride fume and which reduces the copper values in the cuprous chloride to molten elemental copper. The zinc chloride fume, containing minor quantities of cuprous chloride, is condensed and reduced by contact with aluminum scrap to convert aluminum in the scrap to an aluminum chloride fume and forming a molten zinc-copper-aluminum alloy product. If desired, the aluminum chloride fume can be oxidized with steam to yield an aluminum oxide product and by-product hydrochloric acid.
