Midrex is direct reduction process using a shaft-reactor and is developed by Midrex/Kobe Steel. Iron ore pellets, lump iron ore or a combination of pellets and ore are reduced in a vertical shaft or reduction furnace to metallic iron by means of a reduction gas.
Directly reduced iron is a product of iron (steel) direct reduction from ores in the solid state (at a temperature lower than the melting point) and without coke – DRI ( TN: direct- reduced iron ), HBI ( TN: Hot-Briquetted Iron ), sponge iron.

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. Unlike the conventional process, the process does not require coking coal; the coke ovens in a
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.
The Convent plant receives imported ferrous oxide from Brazil, Canada and Norway, conveying the iron ore from a Mississippi River terminal to the direct reduced iron plant.
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.

Midrex Process for Direct Reduction of Iron Ore. Midrex is an ironmaking process, developed for the production of direct reduced iron (DRI). It is a gas-based shaft furnace process is a solid state reduction process which reduces iron ore pellets or lump ore into DRI without their melting using reducing gas generally formed from natural gas.
THE HEART OF THE MIDREX® PROCESS IS THE MIDREX® SHAFT FURNACE. AS A KEY COMPONENT OF THE MIDREX® DIRECT REDUCTION PROCESS, THE MIDREX SHAFT FURNACE IS THE MOST FLEXIBLE AND VERSATILE REDUCTION VESSEL FOR DRI PRODUCERS. The MIDREX® Shaft Furnace can use natural gas or a syngas from coal or coke oven gas as its reductant.
