The sponge iron is melted in the electric arc furnace and induction furnace to produce mild steel and special alloy steel. In the absence of coking coal and good quality iron ore, the sponge iron technology became popular. The use of non coking coal and natural gas as the reducing agent helped in production of sponge iron The sponge iron became an .
Directreduced 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. The reducing gas is a mixture majority of hydrogen (H2) and carbon monoxide (CO) which acts as reducing agent.

Direct reduced iron (DRI) is also known as sponge iron. It is produced by the reduction of iron ore (in the form of lumps or pellets) by either noncoking coal or a reducing gas produced by reforming of natural gas. The reducing gas can also be produced by the gasification of coal.
Sulphur content: The sulphur content in sponge iron is controlled by adding 16mm of limestone/dolomite along with feed materials which picks up sulphur from the coal preventing the sulphur pick up in sponge iron. The sulphur content in sponge iron can be controlled in the range to 0,025%.
Directreduced 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 elementary carbon produced from natural gas or coal. Many ores are suitable for direct reduction.
The process flow diagram of conventional coal based sponge iron plant is shown in Fig. 1. The operating data, shown in Fig. 1, is taken from a typical Indian coal based sponge iron plant where iron ore, feed coal and dolomite are fed to the rotary kiln. A separate conveyor collects different size fractions of coal for injection into the kiln
