The global sponge iron market reached a value of USD 0.76 Billion in 2024. According to IMARC Group, the market is projected to reach USD 0.81 Billion by 2033, at a projected CAGR of 6.5% during 2025-2033.
The sponge iron market is influenced by the changes in the steel industry and the raw material market. One of the main factors that contribute to the growth of the sponge iron market is the use of electric arc furnaces and induction furnaces in the steel industry. The use of these furnaces requires cleaner iron, and sponge iron is a good substitute for steel scrap, especially when the quality of steel scrap is limited. Another factor that contributes to the growth of the sponge iron market is the volatility of the global steel scrap market. The fluctuations in the steel scrap market make steel producers look for other alternatives. Sponge iron provides consistent chemistry and lower residual levels, which help steel producers to produce high-quality steel. Energy and environmental factors also affect demand. Sponge iron production, especially when integrated with gas-based or efficient coal-based systems, can provide lower overall emissions than traditional blast furnace-based routes. In some geographies, sponge iron is promoted as an enabling material for low-carbon steel production routes, especially when combined with cleaner reductants. Availability of resources also helps to fuel market expansion. Nations with large iron ore deposits and coal or natural gas resources are poised to produce sponge iron within their own borders, cutting their reliance on imported metallics. This is consistent with country-level plans to enhance their steel value chains and enhance raw material security. The expansion of infrastructure, construction, automotive, and manufacturing industries also helps to sustain global steel demand, indirectly fueling sponge iron demand. Its use as a versatile, scalable, and quality-assured iron supply option ensures continued relevance in established and developing global steel markets.One of our clients reached out to us to conduct a feasibility study for setting up a medium scale DB真人旗舰·集团:sponge iron manufacturing plant.
Manufacturing Process: The production process of sponge iron, also known as direct reduced iron (DRI), includes the reduction of iron ore in the solid state without melting the iron ore. The process starts with iron ore prepar🔯ation, where iron ore lumps or pellets of a certain size and quality are chosen, screened, and cleaned to have similar reduction properties. These are then fed into a reduction reactor, which can be either a rotary kiln or a shaft fur🍬nace, depending on the production method.
In the coal-based method, which is mostly done in rotary kilns, iron ore is agitated with non-coking coal and limestone or dolomite flux. This is then fed into a long, inclined rotary kiln, where it is heated to temperatures of about 900-1,050°C. As the kiln rotates, coal produces carbon monoxide, which then reacts with iron oxides to remove oxygen and produce metallic iron. The iron ore is in the solid state throughout the process and has a porous, sponge-like structure. In the gas-based process, iron ore pellets are reduced by a gas consisting of hydrogen and carbon monoxide produced by the reforming of natural gas. The gas moves counter-currently to the falling iron ore, resulting in efficient removal of oxygen and the production of high-quality sponge iron. The reduced sponge iron is then removed and cooled in an inert atmosphere to avoid reoxidation. The material can then be screened, stored, or processed into hot briquetted iron (HBI) for easier handling and transportation.
