declining price of shale gas, there has been an upsurge in the installation of DRI plants in the US [44]. Shaft furnaces, rotary kilns, rotary hearth furnaces and fluidized bed reactors are used for direct reduction of iron ore. Most of the DRI plants use shaft furnace reactors developed by MIDREX [43] and HYL-Energiron [45] technologies.

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).

Steel can be produced via two main processes: either using an integrated blast furnace (BF)/basic oxygen furnace (BOF) or an electric arc furnace (EAF). While integrated players produce steel from iron ore and need coal as a reductant, EAF producers use steel scrap or direct reduced iron (DRI) as their main raw material.
