ABSTRACT:
A method for processing metallurgical waste characterized by collecting metallurgical waste containing oxides of such metals as lead and zinc which when reduced form volatile and non-volatile metals; compacting a mixture of metallurgical waste, carbonaceous material and silica into pellets; heating the pellet at a temperature sufficient to reduce the oxides to vapors of elemental metals; and condensing the vapors to liquid or solid status of the elemental metal.
