    Emerging Technologies for Iron and Steelmaking - TMS. By 1350 BC to 1100 BC, the production of ferrous metals from iron ore had ..... Several processes based upon the direct reaction of coal and iron ore in a rotary kiln, ... a rotary hearth furnace to reduce composite pellets containing both iron-oxide .... in South Africa, is capable of producing steel directly from coal and iron ore.Primus / Steelmaking Residue Treatment / Our Activities ...primus The Primus process is well adapted for processing dust, which contains more than 5 % of zinc and is typically generated by EAF mini-mills. When fed with EAF dust, Primus produces hot metal of a quality similar to the one produced by a blast furnace, zinc oxide concentrate (more than 55 % Zn) and an inert slag which can be used for road construction.Sponge Iron Process for Manned Space ExplorationTwo theoretical applications of the sponge iron process were also investigated within this study: hydrogen production with carbon monoxide as SIR reducing agent, and storage of hydrogen by means of a REDOX reaction of a contact mass.WELSPUN STEEL LIMITEDSponge iron is a metallic product produced through direct reduction of iron ore in the solid state. It is a substitute for scrap and is mainly used in making steel through the secondary route. The process of sponge iron making aims to remove the oxygen from iron ore.iron reduction furnace pelletizer priceMidrex Process for Direct Reduction of Iron Ore. Midrex is an ironmaking process, developed for the production of direct reduced iron (DRI). It is a gas-based shaft furnace process is a solid state reduction process which reduces iron ore pellets or lump ore into DRI without their melting using reducing gas generally formed from natural gas.Direct reduced iron - WikipediaDirect reduced iron, also called sponge iron, is produced from the direct reduction of iron ore to iron by a reducing gas or elemental carbon produced from natural gas or coal. Many ores are suitable for direct reduction. Direct reduction refers to solid-state processes which reduce iron oxides to metallic iron at temperatures below the melting point of iron. Reduced iron derives its name from these processes, one example being heating iron .
