    The mechanism of reduction of iron oxide by hydrogen

    Precipitated iron oxide samples were characterized using the temperatureprogrammed reduction method to investigate the reduction behaviors. The twostep reduction was observed. Fe 2 O 3 was reduced to Fe 3 O 4 and then reduce to metallic Fe.

    Direct reduced iron Wikipedia

    Direct reduced iron (DRI), also called sponge iron, is produced from the direct reduction of iron ore (in the form of lumps, pellets, or fines) to iron by a reducing gas or elemental carbon produced from natural gas or coal. Many ores are suitable for direct reduction.

    The Extraction of Iron Chemistry LibreTexts

    The common ores of iron are both iron oxides, and these can be reduced to iron by heating them with carbon in the form of coke. Coke is produced by heating coal in the absence of air. Coke is cheap and provides both the reducing agent for the reaction and also the heat source.
