The ambition is that a first factory, with the capacity to produce 50kt of fossil-free sponge iron per year, will be completed in 2026. "Our process requires less than a tenth of the electricity per ton of sponge iron produced compared to the electrolysis-based initiatives," claim representatives of FerroSilva today on the Swedish website Dagens …
India is the world's largest producer of sponge iron, accounting for 13 per cent of the global production 8. Sponge iron is produced using either coal or natural gas. Since coal is available in India, the sector largely depends on coal based sponge iron which contributes about 80 per cent of the total capacity in the country9.
Stockholm/Sweden – The Hybrit pilot plant in Luleå, Sweden has completed test production of sponge iron and demonstrates that it is possible to use fossil-free hydrogen gas to reduce iron ore instead of using coal and coke to remove the oxygen.Production has been continuous and of good quality. Around 100 tons have …
The production of sponge iron from these wastes could be considered a method of beneficiation. ... scheme-2 is selected as the best possible design for sponge iron plants, proving process ...
The sponge iron was then hammered to remove impurities and produce iron weapons and tools. The low cost of natural gas has made the direct reduced iron (DRI) process more attractive to …

Dr. Chatterjee is recognised all over the world as an authority in the field of process metallurgy, particularly in the area of alternative method of iron production …
Firstly, it has relatively low process temperature (1000e1100 C), direct mixing does not need granulation, and the production cost is low; Secondly, Primus process is very flexible, which can be ...
In the Direct Reduced Iron (DRI) plant, production of sponge iron using a solid reductant involves reducing iron ore (lumps/pellets) with a carbonaceous material such as coal. The reduction is carried out in a rotary kiln (which is inclined and rotates at a pre-determined range of speeds) at a stipulated temperature (850°C -1,500°C).
Outlook: synthesizing green ammonia and tuning the iron reduction process. The ammonia-based direct reduction connects two of the most CO 2 intensive industries, the steel and ammonia production, and paves the way to a sustainable transition together. Moreover, by using ammonia the logistic and energetic …
Sponge iron powder . The Höganäs process is a direct reduction method for production of sponge iron powder using magnetite ore (Fe3O4) and carbon as raw materials. The reduction process takes place in a gas fired tunnel kiln at around 1200°C for 60 hours producing a sponge iron cake that is crushed, milled and

The shift towards carbon dioxide-free sponge iron begins in Gällivare, where our new demonstration plant will pioneer the industrial-scale implementation of the HYBRIT process. This milestone facility aims to yield around1-1.5 …
The iron sponge technique originated in Europe more than 100 years ago, and the earliest operators used a naturally occurring form of hydrated iron oxide known as bog iron or bog ore. As refinements were made in the process, it was found that more efficient sulfur removal could be attained by uniformly distributing the iron oxide hydrate …
This product is known as direct reduced iron (DRI) or sponge iron. Processes that produce iron by reduction of iron ore (in solid state) below the melting point are generally classified as DR ...
Paul Wurth developed PRIMUS process, which uses multiple hearth furnace for processing of EAFD, which contains more than 5 wt% Zn. When it is fed with EAF dust, it produces highly metalized sponge iron at comparatively lower temperature and along with ZnO product. PRIMUS is of a …
Some of the most common Sponge Iron uses include: Steelmaking: Sponge Iron is commonly used in steelmaking as a substitute for scrap metal. It has a high iron content and low levels of impurities, making it an ideal feedstock for steel production. Foundry Industry: Sponge Iron is used in foundries to produce high-quality cast iron …
Smelting Reduction. Figure 2: The smelt reduction vessel (SRV) is the core technology component of the Hismelt process. Source: RioTinto While years of ironmaking technology innovations have optimized blast furnace productivity, two alternative processes—smelting reduction and direct iron reduction— are growing in adoption. The …

For years, the iron and steel industry has been in search of new processes for an efficient production of steel as well as for the recycling of its by-products, especially for those containing zinc. Considering these objectives, Paul Wurth S.A., in cooperation with ProfilARBED, has developed a process using the multiple-hearth …
The sponge iron process. The longest established of these processes is the sponge iron process, the leading example of a family of processes involving solid state reduction of an oxide. In the process, selected magnetite (Fe3O4) ore is mixed with coke and lime and placed in a silicon carbide retort.
