Magnetite ore of nagaland—its mineralogy and reduction kinetics

Vaish, A K and Nayak, B and Goswami, M C and Singh, S D and Singh, D P and Gupta, R C (2010) Magnetite ore of nagaland—its mineralogy and reduction kinetics. In: Proceedings of the XI International Seminar on Mineral Processing Technology (MPT-2010), Dec 2010, NML Jamshedpur, India.



The magnetite body near Pokphur in the Kiphere district of Nagaland is geologically quite different and a rare type of occurrence associated with ophiolite. Mineralogical studies reveal the presence of magnetite, chromite and hematite followed by goethite, ilmentite, trevorite, pentlandite and millerrite. Magnetite grains are weathered to various degrees and sometimes fractured. Reduction studies indicate that in gas-solid system considerable reduction of magnetite ore takes place in initial 60 minutes, further the rate of reduction becomes slow. In gas-solid system the percentage reduction of magnetite ore is considerably more compared to solid-solid systems.
