Typical sources of carbon monoxide are natural gas, coal gas, and coal. Other energy inputs into the production process often include oil and electricity. Since much of the energy used is in the form of natural gas (e.g., Mexico produces virtually all its direct reduced iron with natural gas), most direct reduced ironSL/RN process - Outotec,Outotec as an investment; Share information; Disclosure policy; Corporate governance; IR services

Our comprehensive portfolio of technologies and services covers the entire ore to metal value chain. Our research and development capabilities along with pilot plants support you in choosing the best processing technology for your raw materials.Direct Reduction - Iron and Steelmaking,The basis of the direct reduction process is that solid sponge iron is produced by removing oxygen from the ore in a shaft furnace, rotary kiln furnace or fluidised bed. Sponge iron can be produced in the form of Direct Reduced Iron (DRI), Hot Briquetted Iron (HBI) and Cold Briquetted Iron (CBI); also Low Reduced Iron (LRI), which is pre-reduced iron ore with a reduction and metallisation,Direct reduced iron - Wikipedia,Direct reduction refers to solid-state processes which reduce iron oxides to metallic iron at temperatures below the melting point of iron. Reduced iron derives its name from these processes, one example being heating iron ore in a furnace at a high temperature of 800 to 1,200 °C (1,470 to 2,190 °F) in the presence of the reducing gas syngas , a mixture of hydrogen and carbon monoxide .Circored hydrogen-based reduction - Metso Outotec,Direct use of iron ore fines without prior agglomeration, such as pelletizing or sintering.

Circofer coal based reduction - Metso Outotec
Circofer pre-reduction essentially consists of a circulating fluidized bed (CFB) where the iron ore is reduced by carbon monoxide and hydrogen gas generated from in-situ coal gasification. The offgas from the CFB is used to pre-heat the iron ore in a 2-stage suspension preheater. The iron ore is then further heated up by recycled char and through partial combustion of coal with oxygen in the,Hydrogen-based Reduction of Iron Ores,• Hydrogen-based direct reduction for iron ore fines .

The reducing agents are carbon monoxide and hydrogen, coming from reformed natural gas, syngas or coal. Iron ore is used mostly in pellet and/or lumpy form. The chemical reactions involved in the direct reduction of iron are the,Detailed Modeling of the Direct Reduction of Iron Ore in a,,The direct reduction (DR) of iron ore, usually followed by electric arc steelmaking, is an alternative route to the standard, blast furnace, basic oxygen route for making steel. Annual DR iron production (86 Mt in 2017) remains small, compared to the production of 1180 Mt of blast furnace pig iron [1]. However, an attractive feature of DR, compared to blast furnace reduction, is its,
