ABSTRACT:
A method for direct reduction of iron ore containing sulfur in a shaft type reduction furnace wherein two separate streams of spent reducing gas are withdrawn from the reduction furnace. One stream, being substantially free of sulfur, is recycled through a catalytic reformer to produce fresh reducing gas, the other stream, containing sulfur, is utilized in the process where sulfur is not of consequence.
