2021-8-25 HYFOR (Hydrogen-based Fine-Ore Reduction) is a novel direct reduction process for iron ore fines concentrates from ore beneficiation, developed by MHI Group company Primetals Technologies. It builds on fluidized-bed reduction technology, does not require any agglomeration (such as sintering or pelletizing), and uses on 100% hydrogen as a feedstock.

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.

2021-10-28 Direct reduction of iron is the chemical removal (reduction) of oxygen from iron ore in its solid form. The iron used in the steelmaking process is currently chemically reduced from iron ore through the use of fossil resources – natural gas or coal. This process is known as Direct Reduced Ironmaking (DRI). Carbon combines with the oxygen in ...

Iron ore is a mineral that contains iron (Fe) and must be refined before use. To refine this stone, the fusion and reduction processes must be performed. It is one of the most abundant metal rocks on the Earth and it can be said that about 5% of the Earth's entire crust is iron oxide.

2017-6-17 Iron ore can also be converted to steel through the Direct Reduced Iron (DRI) process by directly reducing iron ore with a reducing gas (eg. H 2 and CO - commonly produced by reforming natural gas). The DRI process uses 20%more energy overall than the BF-BOF process, but has 20%lower CO 2 emissions, resulting from the use of natural gas rather ...
