Direct reduced iron (DRI), also called sponge iron, [1] is produced from the direct reduction of iron ore (in the form of lumps, pellets, or fines) into iron by a reducing gas which contains elemental carbon (produced from natural gas or coal) and/or hydrogen. When hydrogen is used as the reducing gas no carbon dioxide is produced.
JSW Ispat Steel has two integrated steel plants, located at Dolvi and Kalmeshwar in the state of Maharashtra.The 1,200 acres (4.9 km 2) Dolvi complex houses the 30 lakh tonne per annum hot rolled coils plant, which combines the latest technologies – the Conarc process for steel making and the compact strip process (CSP) – introduced in Asia.

The company manufactures and sells sponge iron, mild steel slabs, rails, mild steel, structural, hot rolled plates, iron ore pellets, and coils. [6] Jindal Steel and Power set up the world's first MXCOL plant at Angul, Odisha that uses the locally available and cheap high-ash coal and turns it into synthesis gas for steel making, reducing the ...
The Iron and Steel industry in India is among the most important industries within the country. India surpassed Japan as the second largest steel producer in January 2019. [ 1 ] As per worldsteel , India's crude steel production in 2018 was at 106.5 million tonnes (MT), 4.9% increase from 101.5 MT in 2017, which means that India overtook Japan ...
The HIsarna ironmaking process is a direct reduced iron process for iron making in which iron ore is processed almost directly into liquid iron ().The process combines two process units, the Cyclone Converter Furnace (CCF) for ore melting and pre-reduction and a Smelting Reduction Vessel (SRV) where the final reduction stage to liquid iron takes place.

Subsequently, the iron oxides are gradually altered into ferronickel or metallic iron. The metal produced is in the form of metallic sponge particles that are finely dispersed in the powdery gangue. Reduction is complete by the end of the furnace, and there is a minimal amount of CO produced.
