Iron Ore (Second Edition)
Depending on the conditions used for final reduction of iron ore, alternative ironmaking technologies are typically divided into direct reduction (DR) and smelting reduction (SR) processes. The DR process involves the removal of oxygen from iron ore in its solid state at 750–1100°C using solid and gaseous reductants, such as natural gas …
DRI production | International Iron Metallics Association
DRI production. Direct reduction of iron is the removal of oxygen from iron ore or other iron bearing materials in the solid state, i.e. without melting, as in the blast furnace. 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.
Iron Ore Briquettes
Main advantages of iron ore briquettes. Lower CO2 emissions. Briquettes emit less carbon dioxide than traditional agglomeration processes (pelletizing and sintering). It can reduce CO2 emissions in the steelmaking chain by up to 10%. Lower gas emissions. Iron ore briquettes reduce emissions gases such as sulfur dioxide and nitrogen oxide.
