The steel industry represents about 7% of the world’s anthropogenic CO2 emissions due to the high use of fossil fuels. The CO2-lean direct reduction of iron ore with hydrogen is considered to offer a high potential to reduce CO2 emissions, and this direct reduction of Fe2O3 powder is investigated in this research. The H2 reduction reaction kinetics and fluidization characteristics of fine

Iron ore is used mostly in pellet and/or lumpy form. Oxygen (O2) is removed from the iron ore by chemical reactions based on H2 and CO for the production of highly metalized DRI. In the direct reduction process, the solid metallic iron (Fe) is obtained directly from solid iron ore without subjecting the ore or the metal to fusion.

Iron ore is pre-heated and fed into a reduction shaft, where it is converted to direct reduced iron (DRI) and further compacted to hot briquetted iron (HBI). Hydrogen generated in an electrolysis unit is pre-heated in a condenser before being supplied to the shaft where it acts as the reducing agent.

Expanding direct reduction iron ore pellet volumes from Russia, Ukraine and Canada, and US pellets helping meet a recovery in European steel demand are shifting pellet supplies available in the Atlantic and Middle East, setting up dynamic pricing shifts under long-term contracts, according to iron ore and steel market participants.

The downturn ex-China has prompted iron ore exporters to divert more supply to China, boosting pellet trade from Russia, Ukraine, Sweden and India. Brazil is the world''s biggest exporter of pellets, despite a drop in shipments from 54 million mt in 2015 to 27 million mt in 2019. Key to this was the Fundão tailings dam disaster in late 2015

SL/RN Process. The so-called Stelco-Lurgi/Republic Steel-National Lead (SL/RN) process is a widely used coal-based DRI-making process which uses a rotary kiln. The process uses lump ore, pellets, beach sand or ilmenite ore and solid carbon to produce hot or cold DRI. The process operates at high temperature and atmospheric pressure.

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.
