descends by gravity flow and is contacted by upward flowing reducing gas. The reducing gas, which is primarily hydrogen and carbon monoxide, reacts with the iron oxide to reduce (remove the oxygen content) and carburize the material prior to discharge. From there the product can be discharged as CDRI, HDRI, HBI or any combination simultaneously.

Iron (III) oxide or ferric oxide is an inorganic compound with the formula Fe2O3. It is one of the three main oxides of iron. As the mineral known as hematite, Fe2O3 is the main source of the iron for the steel industry. Fe2O3 is ferromagnetic, dark red, and readily attacked by acids. Iron (III) oxide is often called rust.
Natural iron oxide pigments are costly as compared with its synthetic counterpart owing to high cost of raw material. Natural iron oxide pigments are more durable and have excellent tinting strength as compared with synthetic pigments. Most of the natural iron oxide pigments are employed in paints coatings and other automotive applications.
Iron Oxide is generated by reclaiming it from acid using the Ruthner Spray process. This process ensures the Iron Oxide obtained is consistent in quality and high in purity. Due to high purity and excellent quality, Tata Steel by-product Iron oxide is quite popular among the ferrite magnetic manufacturers for

process of sintering. (a) Zone of Sinter The gross physical character of this zone is established upon the solidification of the fluid slag matrix, but the physical and chemical cheques occur just after solidification such as oxidation of magnetite to hematite, grain growth of iron oxide crystal.
Iron oxide ores extracted from the Earth are allowed to absorb carbon by a reduction process. In this natural reduction reaction, as the iron ore is heated with carbon, it results in a pop-marked surface, hence the name sponge iron. The commercial process is a solid solution reduction, also called direct-reduced iron (DRI). In this process, the iron ore lumps, pellets, or fines are heated in a furnace at 8001500C (14702730F) in a

Jul 28, 2021 Iron oxide, in pellet or lump form, is introduced through a proportioning hopper at the top of the shaft furnace. As the iron ore descends through the furnace by gravity flow, it is heated, and the oxygen is removed from the iron ore (reduction) by counterflowing gases that have a high H and CO content.

The carbon monoxide (co) produced as above reduces iron oxide to metallic iron. Fe2o3 3 CO - 2Fe 3 Co2 However, the reduction form oxide to metal does not occur in one step, but by gradual removal of oxygen giving, rise to various intermediary oxides. The reduction sequence can be expressed as follows
In case of synthetic Rutile the iron oxide impurities could be brought down from 2.5 to 0.5 per cent while in iron ore slime, the iron oxide could be enriched to 70 from 60 per cent in a single pass. These trials have proved the efficacy of the system in separating weakly magnetic impurities of micron size from the basic minerals.
