DRI, also known as sponge iron, is the product of reducing iron oxide in the form of iron ore and steel plant wastes into metallic iron, below the melting point of iron and typically in the range of 800–1200 °C. Iron oxide is charged into shaft furnace, rotary kiln, or fluidized beds in the form of pellet, iron ore lumps, or fines. The reduction takes place using …

2.1 Midrex Process. Midrex is the most successful gas-based DR process; it is a continuous process. It is basically a countercurrent process where a hot and highly reducing gas (95vol.% of this gas mixture being hydrogen and carbon monoxide with a ratio of H 2:CO varying from 1.5 to 1.6) reduces lump iron ore or pellets to metallic iron as …
In the SL/RN process (fig 1), reduction of iron oxide is carried out in a refactorylined rotary inclined from the feed to the discharge end. The slope of the kiln is ca.1.5-2.5 % depending on the feed materials. The process uses lump ore, pellets, beach sand or ilmenite ore and solid carbon to produce hot or cold DRI. ...

The process of making sponge iron aims to expel oxygen from the iron ore and increase its quality. Compared to conventional blast furnaces, this method reduces steel production costs and energy usage. It is also environmentally friendly since it does not produce any greenhouse gases.
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.
