environmental impacts of direct reduced iron
Itakpe iron ore deposit comprises variable constituents of hematite and magnetite and particle sizes. This deposit with an Fe content of 35% consists of fine ores occurring in thin layers and coarse-grained mixed components. Direct-reduced iron (DRI) is the direct reduction of iron ore to iron n steel making.
ENVIRONMENTAL - ASPECTS OF THE DIRECT REDUCTION ROUTE
Whilst the potential environmental impacts of the direct reduction route to steel making are less serious than those of the classical blast furnace and scrap melting routes, there remain some environmental problems. Supplementary information can be found in the UNEP overview and technical review on the
Direct-Reduced Iron - an overview | ScienceDirect Topics
05/01/2012· By using direct reduced iron, steel makers can dilute lower grade ores and lower cost ferrous scrap to attain acceptable levels of contamination in the mix. If direct reduced iron pellets are substituted for pelletized ores in blast furnaces, the amount of coke per ton of pig iron would be cut. However, reductions in the coke rate could result in shortages of coke
Making iron with less energy and environmental impact,
H2 Hamburg – at our Hamburg site we are planning a €65 million project to use hydrogen on an industrial scale to reduce iron ore in a direct reduced iron (DRI) furnace. Hydrogen currently provides 50% of the reaction in DRI steelmaking, with the remainder coming from natural gas. There is potential for hydrogen to provide 100% of the reaction, removing the need for fossil

Direct reduced iron - Wikipedia
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) into iron by a reducing gas or elemental carbon produced from natural gas or coal.Many ores are suitable for direct reduction. Direct reduction refers to solid-state processes which reduce iron oxides to metallic iron at temperatures
