  • Direct Reduced Iron and its Production Processes –

    In the direct reduction process, the solid metallic iron (Fe) is obtained directly from solid iron ore without subjecting the ore or the metal to fusion. Direct reduction can be defined as reduction in the solid state at O2 potentials which allow reduction of iron oxides, but not of other oxides (MnO, and SiO2 etc.), to the corresponding elements.

  • The Process - Plant - Texas LLC

    Direct Reduction – The cleanest and safest way of iron making Most naturally occurring iron oxide has the composition of hematite (Fe2O3) and contains about 30% oxygen. The direct reduction process removes this bonded oxygen in the iron ore pellets at elevated temperatures by a reducing gas, which is produced from natural gas.

  • Direct Reduction Process - an overview |

    Direct reduction (DR) processes have been in existence for several decades. The evolution of direct reduction technology to its present status has included more than 100 different DR process concepts, many of which have only been operated experimentally. Most were found to be economically or technically unfavorable and abandoned.
