  • 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) to iron by a reducing gas or elemental carbon produced from natural gas or coal. Many ores are suitable for direct reduction.

    Plant facilities. Coal acts as the reductant to romove oxygen from iron ore. The process of reduction causes micro pores in the ore body turning it porous. Directly reduced iron looks like sponge in texture due to pores and hence is called sponge iron. Iron Ore after due reduction inside the kiln is discharged to a rotary cooler of 3.5 mtr.

  • What is Sponge Iron? (with pictures) wisegeek

    The iron ore is often in the form of pellets or lumps and is subjected to a reduction process that is created by the use of a reducing gas that emits from coal or a natural gas source. This type of iron can be produced in several different types of furnaces including coke or charcoal ovens blast furnaces and basic oxygen furnaces.
