Sponge iron making is a process in which iron ore lumps (typically 5mm-18mm size) are tumbled with a 'select' grade of iron-coking coal little dolomite inside an inclined rotary kiln and control combusted in the presence of air for about 12 hours before the products are air cooled, magnetically separated, screened and size wise in finished ...
The Corex Process is a smelting reduction process created by Siemens VAI as a more environmentally friendly alternative to the blast furnace.Presently, the majority of steel production is through the blast furnace which has to rely on coking coal. That is coal which has been cooked in order to remove impurities so that it is superior to coal. The blast furnace requires a sinter plant in order ...
Offering the highest iron recovery, magnetite sponge iron can be a revolutionary turn in the Indian metallurgical industry, shares Soumitra Mohanty, the executor of the success trials of the above project. India has been the largest producer of sponge iron globally, since 2003. Since 2014, India's contribution to the sponge iron has crossed 25%.
Productions of sponge iron and sponge iron based steel plants are continuously increasing and we expect that in next two to three months we will come to preCovid 19 level. - If we look into the JPC data from April January–, 2020, the production of sponge iron have shown negative growth of 12% as comparedto the similar period of last year.
The sponge iron is also known as Direct Reduced Iron, Hot Briquettes Iron or metalized Iron. With the domestic steel industry picking up during the past year and prices moving up in leaps and bounds, India has emerged as the world's largest producer of sponge iron (or direct reduced iron), accounting for around 16 per cent of the global output.

The COREX process is a two-stage process, as is shown in Figure 1.1.40.In the first step, iron ore is reduced to sponge iron in a shaft furnace by means of reducing gas. In the second step, the reduced iron is melted in the melter–gasifier vessel.
DR process, DRI, HBI, Iron making. Metallization, reformed natural gas, residual elements, Rotary kiln, Direct Reduced Iron and its Production Processes. Direct reduced iron (DRI) is the product which is produced by the direct reduction of iron ore or other iron bearing materials in the solid state by using non-coking coal or natural gas.
COREX PROCESS Charge is charged into a reduction shaft where they are reduced to direct reduced iron (DRI) by a reduction gas moving in counter flow. Discharge screws convey the DRI from the reduction shaft into the melter –gasifier. In Melter-gasifier final reduction and melting takes place. Hot metal and slag tapping are done as in ...
They stopped production in July 2015 when steel, and along with that sponge iron prices, collapsed, but they have come back to life more recently. As a signatory to the Paris Agreement on climate change, India, which accounts for over 4% of global emissions, will have to reduce its carbon footprint by 33-35% by 2030 from the 2005 level.
