India is the world's largest producer of sponge iron, most of which is produced primarily through the coal based method of production. 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.
India is the largest producer of direct reduction of iron (DRI), popularly known as sponge iron and accounted for about 39.3% of the global production in 2020. India's growing economy will require an increase in steel production to meet the demands of sectors such as housing and infrastructure, automobile, engineering, etc.
It has been estimated that approximately 65-75% of sponge iron production cost is attributed to the cost of raw materials (Indian Bureau of Mines, 2011). As a measure to improve process flexibility and reduce operational costs, DR processes resort to the use of fine ore instead of lumps, as well as cheap waste gases (Friedl et al., 2018).

This way we'll strengthen our position in the value chain and increase the value of our products by selling more refined iron, while enabling significantly reduced carbon dioxide emissions throughout the entire value ...

This book provides a fascinating study of the very important emerging field of direct reduction in which iron ore is 'directly reduced' in the solid-state, using either natural gas or non-coking coal, to produce a highly metallised material, referred to as sponge iron (or direct reduced iron). This intermediate product is subsequently melted in electric arc furnaces or induction furnaces ...
Further, it is melted at 1100° C which produces sponge iron. Let's understand in-depth the uses and applications of sponge iron, the production process, plants and more. Sponge iron plants in India. Since the year 2002, India has become the largest producer of sponge iron worldwide and 20% of the sponge iron is produced by India itself.
In the world of production management, your CV should echo the nature of your work. Simple, straightforward and active. The bulk of production management involves taking charge and getting things done. Be it a small shop floor or a …
The hot gases from the rotary kiln used for sponge iron production enter the post-combustion chamber (PCC) placed next to the kiln. These gases (1023–1223 K) contain unused carbon monoxide (CO) and unburnt …
1995 OSIL supplied the technology to Llyods India for their sponge iron production plant at Chandrapur, Maharastra. The OSIL process uses a rotary kiln of 3.5mtr diameter and ...

SSAB, LKAB and Vattenfall, the three owners, launched the HYBRIT initiative in 2016. The pilot plant for the test production of sponge iron started operation on August 31, 2020 and on March 24, 2021, Gällivare was chosen for the site of the planned demonstration plant for the production of fossil-free sponge iron at an industrial scale.
Sponge iron means porous iron produced by direct reduction process.Direct reduction (DR) process is a solid-state reaction process (i.e. solid–solid or solid–gas reaction) by which removable oxygen is removed from the iron ore, using coal or reformed natural gas as reductants, below the melting and fusion point of the lump ore or agglomerates of fine ore [].
2 KILN BASED SPONGE IRON PRODUCTION PROCESS Rotary kilns are found in many processes that involve processing of solids. This study focuses on sponge iron kiln based process. The chemical process involved in making sponge iron removes oxygen from iron ore by using a reducing agent in the form of non-coking coal [Patra et al, (2005)]. The ...
Sponge iron is produced by low-temperature reduction of iron ore in a rotary furnace, shaft furnace, or reactor. Since the reduction temperature is lower than the melting temperature of the ore, the iron ore still maintains the shape of the ore after solid-state reduction, and has a porous and low-density sponge-like structure, hence the name ...

evident from the steep rise in world DRI production during the past three decades. India, entered the sponge iron industry only in 1980, when the coal based DRI plant of Sponge Iron India Limited (SIIL) was commissioned at Kothagudem, in Andhra Pradesh. 2. The reasons for the tremendous growth of the sponge iron industry
Sponge Iron Formation: In the kiln, the iron oxides are reduced to metallic iron, forming sponge iron with a high porosity. Cooling and Separation: The sponge iron is cooled and separated from the remaining non-metallic components (gangue). Properties and Uses: Sponge iron has high iron content (typically 90% or more) and low levels of impurities.
The HYBRIT process involves removing the oxygen from the iron ore using hydrogen. The reduction occurs at a lower temperature and the result is so-called sponge iron (direct reduced iron). The sponge iron is smelted in a furnace, powered by electricity. The furnace is called an Electric Arc Furnace (EAF).
