Direct reduction is defined as a process in which metallic iron is produced by reducing iron ore or other iron oxide material belo w the melting temperature of any of the material involved.
The chemistry of steelmaking. The big picture.
Most workable iron ores are rich in iron (III) oxide, Fe 2 O 3. Making iron by removing oxygen from the ore is the first step in the manufacture of steel. Reduction and oxidation Removing oxygen chemically from a substance is called reduction. The industrial
Iron Ore Pelletizing Process: An Overview | IntechOpen
2017/7/10· The iron ore production has significantly expanded in recent years, owing to increasing steel demands in developing countries. However, the content of iron in ore deposits has deteriorated and low-grade iron ore has been processed. The fines resulting from the concentration process must be agglomerated for use in iron and steelmaking. This chapter shows the status of the pelletizing …
Production of sponge iron increases 12% in 4 months …
2 · Sponge iron is a metallic product produced through the direct reduction of iron ore in the strong state. It is a substitute for scrap and therefore is mostly applicable in making steel through the secondary route. The procedure of sponge iron making aims to expel
The FINEX Process :: Total Materia Article
In the Finex process, iron ore fines are charged into a series of fluidized-bed reactors. The fines pass in a downward direction where they are heated and reduced to direct-reduced iron (DRI) by means of a reduction gas – derived from the gasifiion of the coal

Direct reduction of iron | SpringerLink
In the blast-furnace process, direct reduction — in contrast to indirect reduction — means the reduction of ferrous oxide by carbon with the formation of CO. The terms “direct reduction of iron,” “direct production of iron,” “cokeless metallurgy,” or “non-blast-furnace metallurgy” are used in the literature to denote new methods for the metallurgical conversion of iron ore
