Iron Ore Reduction Process

[title]

Direct reduced iron - Wikipedia

Direct-reduced iron (DRI), also called sponge iron,[1] is produced from the direct reduction of iron ore (in the form of lumps, pellets, or fines) to iron by a reducing gas or elementary carbon produced from natural gas or coal. Many ores are suitable for direct reduction.Direct Reduced Iron and its Production Processes,,Fig 1 DRI process principle. Major DRI production processes are either gas based or coal based. Feed material in a DRI process is either iron ore sized to 10 to 30mm or iron ore pellets produced in an iron ore pellet plant. In the gas based plant the reactor, the reduction reaction takes place is a shaft furnace.Iron processing | Britannica,Iron processing: Iron processing, use of a smelting process to turn the ore into a form from which products can be fashioned. Included in this article also is a,

Smelting Reduction | Industrial Efficiency Technology,

These processes combine the gasification of coal with the melt reduction of iron ore. Energy intensity of smelting reduction is lower than that of blast furnace, as the for coke production is not needed and the need for ore preparation is reduced.AusIron process - Outotec,Home; Products; Direct Reduction; AusIron process; Outotec® AusIron process.

Corex Process | Industrial Efficiency Technology & Measures

Corex is a smelting reduction process combining a melter gasifier with a reduction shaft. The process takes lump iron ore or pellets, non-coking coal, and oxygen as main inputs. Similar to the blast furnace process, the reduction gas moves in counter flow to the descending burden in the reduction shaft.3A3. Direct Iron Ore Smelting Reduction Process (DIOS),The Direct Iron Ore Smelting Reduction Process (DIOS) directly uses noncaking coal in a powder or granular form, and iron ore without the use of coke or a sintering process, which are normally required in blast furnace processes. The noncaking coal is directly fed to aEXTRACTION OF IRON- EXTRACTION OF IRON FROM,process involves the crushing and washing of ore. Calcination or Roasting of ore: The concentrated ore is now heated in the presence of air. The process of roasting is performed to remove moisture, CO 2, impurities of sulphur, arsenic. Ferrous oxide is also oxidized to ferric oxide.
