    Direct Reduction Process - an overview | ScienceDirect Topics

    The sponge iron formed in the direct reduction process is then melted in an electric arc furnace. In these processes, the iron oxides in the ore are reduced to metallic iron. In the next step, the raw iron is usually dropped into a torpedo ladle car where reagent is added to purify the iron from sulfur.
