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.

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).
