ABSTRACT:
A method and apparatus for the continuous direct reduction of iron ore concentrates utilizing metallic aluminum as a reductant material. The reactant mixture is ignited, and the reaction is permitted to proceed within the confines of a refractory lined vessel, with the exothermic heat of reaction being utilized to maintain superposed layers within the vessel, including a bottom-most layer of molten metallic iron, an intermediate layer of molten slag, and an upper layer of active semi-molten reactant, with suitable means for tapping of molten slag and metal products.
