Upgrading of Low-Grade Manganese Ore by Selective ...
2012-9-26 The utilization of low-grade manganese ores has become necessary due to the intensive mining of high-grade ores for a long time. In this study, calcined ferruginous low-grade manganese ore was selectively reduced by CO, which converted hematite to magnetite, while manganese oxide was reduced to MnO. The iron-rich component was then separated by magnetic separation. The effects of

INNOVATIVE APPROACHES TO MINERAL EXPLOITATION:
2013-2-5 Mineralogy and texture of the Taycilar deposit show conditions that can favour magnetic enrichment of ore at relatively coarse grain size, providing the opportunity to produce a high grade sand final product. Braunite shows a paramagnetic behaviour that is strongly affected by incorporation of elements, like Mg and Fe, substituting Mn.
