The reduction of hematite occurs faster in both cases, with hydrogen and carbon monoxide. The reduction of magnetite with carbon monoxide shows a very low reduction rate. The main reason is the formation of different structures and porosities, which strongly depends on the raw material used, during the reduction .

Iron oxide reduction by carbon in biomass can be divided into two stages: reduction by volatile carbon followed by reduction by nonvolatile carbon. The reduction times of the two stages both decrease with increasing temperature. The first reduction is controlled by gas diffusion, whereas the second stage is dominated by carbon gasification.

To improve the direct alloying of manganese ore in steelmaking, the decomposition and carbon reduction of manganese ore was studied using a differential thermal analyzer and resistance furnace. The remaining material after manganese ore decomposition at 1,600 °C was a mixture of 43 % MnO, 40 % MnSiO 3 and FeO, and 17 % MnSiO 3 .

In conventional smelting, iron ore is combined with a coalderived carbon called coke. The coke reacts with the iron, producing CO 2 and carbon monoxide, leaving pure iron behind. Advertisement
The manganese oxides were reduced to αMn and Mn 23 C 6 and Mn 7 C 3 depending on the carbon to ore ratio. A reduction retardation was accompanied with the reduction of manganese ores which are contaminated with iron oxides [16, 17]. The reduction of Fe 2 O 3MnO 2SiO 2 mixed oxides with CO gas is investigated .
