The process of sponge iron making aims to remove oxygen from iron ore. When that occurs, the departing oxygen causes micro pores in the ore body making it porous. The final product, when observed under a microscope, resembles a honeycomb structure looking spongy in texture, hence the name sponge iron.

Direct-reduced iron (DRI), also called sponge iron, is produced from direct reduction of iron ore (in the form of lumps, pellets or fines) by a reducing gas produced from natural gas or coal. Unlike the conventional process, the process does not require coking coal the coke ovens in a steel plant are expensive and polluting units.
The sponge iron is a substitute for scrap in the electric arc furnace, which can be easily manufactured from indigenously available raw materials at very competitive price. It is the iron ore reduced in solid state by a direct reduction process using natural gas

DRI, also known as sponge iron, is the product of reducing iron oxide in the form of iron ore and steel plant wastes into metallic iron, below the melting point of iron and typically in the range of 8001200 C. Iron oxide is charged into shaft furnace, rotary kiln, or fluidized beds in the form of pellet, iron ore lumps, or fines. The reduction takes place using gaseous reductants (CO H ...

Sponge Iron, also known as Direct Reduced Iron is produced from Hematite Iron ore (5 to 18 mm size) by removing the oxygen by direct reduction process using non coking coal as the fuel and
Sponge iron is the product created when iron ore is reduced to metallic iron, usually with some kind of carbon (charcoal, etc), at temperatures below the melting point of iron. This results in a spongy mass, sometimes called bloom, consisting of a mix of incandescent wrought iron and slag. Sponge Iron is a recognized alternative to steel scrap as a raw material for the
