    When the iron ore particle size decreased to 38 m, almost the whole reduction of the iron ore achieved at 1200 C. The X ray diffraction analysis of this mixture showed that metallic iron phase occupied an important position in the residue. This indicated that the iron ore particle size of 38 m was sufficient to complete the reduction. 3.2.Not all iron ore is created equal. The highest quality and most important iron ores for steelmaking are hematite (Fe2O3) and magnetite (Fe3O4). Hematite is the sought after ore and the preferred raw material in efficient steelmaking mills. It accounts for approximately 95 of South Africa’s iron ore.
