THE FUNDAMENTAL ASPECTS OF IRON ORE REDUCTION

iron product in the liquid state. In contrast, solid-state processes must operate at much lower temperatures which is a significant disadvantage. No sponge iron furnice of comparable size to a blast furnace can produce metal at the same high rate. Thus the kinetics of iron ore reduction is an important fundamental aspect.
