ABSTRACT:
A method for the gaseous reduction of particulate ores to metals in a moving bed, vertical shaft reactor using a reducing gas externally supplied from a solid or liquid fossil fuel gasification unit. The reducing gas is reformed in a reforming zone located within the reactor and treated prior to injection into the reduction zone of the reactor. A portion of the reducing gas produced in a coal gasification unit may be used to cool the metal in the cooling zone of the reactor.
