Abstract

An iron making process and apparatns are disclosed. The process includes a direct reduction step of passing a reducing gas through a bed of (a) an iron-containing material, such as tabular lump ore, and (b) a bed forming material and producing a reduced iron material. The bed forming material is a material that facilitates forming the bed so that there is optimum upward flow of a reducing gas through the bed. The process also includes separating the reduced iron material and the bed forming material. The bed forming material may be re-used in the direct reduction step.
