India is the world's largest producer of sponge iron, accounting for 13 per cent of the global production 8. Sponge iron is produced using either coal or natural gas. Since coal is available in India, the sector largely depends on coal based sponge iron which contributes about 80 per cent of the total capacity in the country9.
Details
For producing the sponge iron through this process requires high grade of iron ore and non coking coal. Gas Based DRI / HBI. In this process route, iron oxides are converted to the DRI / HBI by using natural gas in a vertical shaft furnace. For steel producers, it is a preferred metallic, energy efficient and much more eco-friendly route.

Details
The metallic iron in this process is produced by the reduction of iron oxide below the fusion temperature of iron ore (1535 deg C) by utilizing carbonaceous material present in the non-coking coal. As the iron ore is in direct contact with the reducing agent throughout the reduction process, it is often termed as direct reduced iron (DRI).

The combined effect of above two advantages gives an impact on the process of sponge iron making. Coal being the costliest raw materials for sponge iron making and if very high volatile material (VM) coals are used i.e. (fixed carbon) FC/VM ratio is 1 or less, it would be an ideal reductant to react. However, most of the VM in feed coal …

In the electric steel process, the sponge iron obtained from the direct reduced iron process is used for crude steel making. In general, scrap is also added to this process as well as pig iron from the blast furnace process. These components are then mixed in a special oven. While the pig iron is already liquid, the sponge iron and …
Details
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 …
