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.degree. 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.
