DRI (Sponge Iron) | Metallics | IBMD | Tata Steel
The procedure of sponge iron making aims to expel the oxygen from iron ore. It is produced by direct reduction of iron-ore in solid-state either by reducing gas or non-coking coal at 1000-1050 °C. The resulting iron is highly porous in nature and hence the name sponge iron.

What is Sponge Iron?
This process removes oxygen from the iron ore, leaving a metal with high iron content and low impurities. It is a more efficient process than blast furnace pig iron but still requires substantial processing to make steel. Sponge iron factories have mushroomed in iron ore and coal-rich states like Jharkhand, Odisha, Chhattisgarh, and West Bengal.

WHAT IS SPONGE IRON AND HOW IS IT MADE?
Sponge iron, also called direct reduced iron (DRI), is made from directly changing iron ore (in any form whatsoever) to iron by a cutback gas or carbon, produced from natural gas or coal. It is one of the many raw materials used in …
Smelting sponge iron in electric arc furnace
The HYBRIT process involves removing the oxygen from the iron ore using hydrogen. The reduction occurs at a lower temperature and the result is so-called sponge iron (direct reduced iron). The sponge iron is smelted in a furnace, powered by electricity. The furnace is called an Electric Arc Furnace (EAF).

Sponge Iron
Sponge iron is produced by low-temperature reduction of iron ore in a rotary furnace, shaft furnace, or reactor. Since the reduction temperature is lower than the melting temperature of the ore, the iron ore still maintains the shape of the ore after solid-state reduction, and has a porous and low-density sponge-like structure, hence the name ...
Sponge Iron
Sponge iron means porous iron produced by direct reduction process.Direct reduction (DR) process is a solid-state reaction process (i.e. solid–solid or solid–gas reaction) by which removable oxygen is removed from the iron ore, using coal or reformed natural gas as reductants, below the melting and fusion point of the lump ore or agglomerates of fine ore [].
