Direct Reduction Process - an overview ScienceDirect

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.

DRI production International Iron Metallics Association

DRI production. Direct reduction of iron is the removal of oxygen from iron ore or other iron bearing materials in the solid state, i.e. without melting, as in the blast furnace. The reducing agents are carbon monoxide and hydrogen, coming from reformed natural gas, syngas or coal. Iron ore is used mostly in pellet and/or lumpy form.
