The microwave assisted reduction behaviours of two low grade iron ores having a similar Fe content of 49wt but distinctly different mineralogical and liberation characteristics were studied. Their performances in terms of the iron grade and recovery as obtained from statistically designed microwave (MW) roasting followed by low intensity magnetic separation (LIMS) experiments were compared.In marine deposits, common magnetic minerals include (titano)magnetite (Fe 3–x Ti x O 4), hematite (Fe 2 O 3), goethite (FeOOH), greigite (Fe 3 S 4), and pyrrhotite (Fe 7 S 8). Each of these minerals is suggestive of different depositional and or diagenetic conditions and each can be identified using common rock magnetic techniques.

Although magnetite contains a higher percentage of iron and is easier to process, hematite is the leading ore because it is abundant and present in deposits in many parts of the world. Hematite is mined in some of the largest mines in the world.
Initially the reduction of hematite is a surface controlled process. However, once a thin layer of iron oxides with lower oxidation state (magnetite, wustite) is formed on the surface, it changes to diffusion control. The values of activation energies obtained were DE a 104 and DE a 24kJ mol for the reducing gas mixtures of N 2+CO and N 2.AbstractThis study aims to provide theoretical and technical basis for economical and rational use of high phosphorus oolitic hematite.
