pruduction of iron ore sponge

  • Direct reduced iron - Wikipedia

    Direct reduced iron (DRI), also called sponge iron, is produced from the direct reduction of iron ore (in the form of lumps, pellets, or fines) into iron by a reducing gas which either contains elemental carbon (produced from natural gas or coal) or hydrogen. When hydrogen is used as the reducing gas there are no greenhouse gases produced. Many ores are suitable for direct reduction. 2023年10月17日  Sponge iron adopts direct reduction ironmaking method to obtain iron with sponge-like pores inside.
