Direct reduced iron Wikipedia

Direct reduced 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 elemental carbon produced from natural gas or coal.Many ores are suitable for direct reduction. Direct reduction refers to solid-state processes which reduce iron oxides to metallic iron at temperatures below the melting

The reasons for the success of Sponge Iron Industry in

Therefore, India became the largest producer of sponge iron in the world and accounted for ~24% of the global production in 2016. Furthermore, the coal based sponge iron plants found eminence in India despite low efficiency. This was due to less investment, lower gestation period, easy availability of coal and limited accessibility of gas.
