  • Reduction of Iron Oxides with Hydrogen—A Review

    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 process.
