Iron ore powder was isothermally reduced at K with hydrogen/carbon monoxide gas mixture (from 0vol%H 2 /100vol%CO to 100vol%H 2 /0vol%CO). Results indicated that the whole reduction process could be divided into two parts that proceed in series. The first part represents a doublestep reduction (Fe 2 O 3→Fe3O4→FeO), in which the kinetic condition is ...

Iron ore is a mineral substance which, when heated in the presence of a reductant, will yield metallic iron (Fe). It almost always consists of iron oxides, the primary forms of which are magnetite (Fe 3 O 4) and hematite (Fe 2 O 3 ). Iron ore is the source of primary iron for the world's iron and steel industries.
