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.
