The reduction of the ore. Iron ore is not pure iron oxide it also contains an assortment of rocky material that would not melt at the temperature of the furnace, and would eventually clog it up. The limestone is added to convert this into slag which melts and runs to the bottom. The heat of the furnace decomposes the limestone to give
Midrex Process for Direct Reduction of Iron Ore . Midrex Process for Direct Reduction of Iron Ore. Midrex is an ironmaking process, developed for the production of direct reduced iron (DRI).

But they still each have a negative 1 oxidation state. So the chlorine was neither oxidized nor reduced in this reaction. But this is definitely an oxidationreduction reaction, or a redox reaction, because you had something getting oxidized and something being reduced. Iron was oxidized by the hydrogen, and the hydrogen was reduced by the iron.

slrn process direct reduction iron. Direct Reduced Iron (DRI) is the product of the direct reduction of iron ore in the solid state by carbon monoxide and hydrogen derived from natural gas or coal. Live Chat. ArcelorMittal investigates hydrogen based direct reduction of iron .
This book provides a fascinating study of the very important emerging field of direct reduction in which iron ore is ''directly reduced'' in the solidstate, using either natural gas or noncoking coal, to produce a highly metallised material, referred to as sponge iron (or direct reduced iron). This intermediate product is subsequently melted in electric arc furnaces or induction furnaces
aspects in reduction of iron oxide were investigated. The experimental studies on reduction of iron oxide pellets were performed under wellcontrolled conditions in a setup designed for thermogravimetric investigations. The results indied that the reaction rates by the applied procedure are higher compared to the procedure similar to
