Direct Reduced Iron (DRI), also known as Sponge Iron, offers an alternative steel production route to BF-BOF and Scrap-EAF routes. In DRI, iron ore is reduced in its solid state – unlike BF process where a liquid metal is formed during reduction.
; Sponge iron plant or Direct Reduction Plant (DRP) is designed to produce 350tons of sponge iron per day in a rotary kiln using iron ore, non coking coal and dolomite as the raw materials. The plant consists of the following sub divisions.
Direct Reduction Plant Home > Products > Direct Reduction Plant Direct Reduction is an iron making process for the new era, which utilizes natural gas to reduce iron ore to produce Direct Reduced Iron (DRI).
Direct-reduced 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.

Smelting Reduction Iron (SRI) and Hylsa are currently commercial processes. Hismelt Smelting Reduction Iron and Hi-Oxy coal plants (with a high rate of coal powder injection) are new processes currently available at the pilot plant level.
The direct reduction process. HBI is the product of reducing iron ore with natural gas. This is called the direct reduction process and is an environmentally-friendly production process; a DRI plant uses natural gas which is more environmentally sound than coke. The reduction process takes place in the reduction tower.
