ABSTRACT Waste materials containing metal oxides and/or metals and their salts are converted to useful products. The waste materials are combined in such proportions that when heated, they form a composite that becomes molten and pourable at temperatures below about 1600°C. Provision is also made for converting some of the metal oxides in the molten material to free metal which is then separated from the molten material. A modified cupola can be used to generate the temperature and reducing conditions suitable for carrying out the process.
