  • Magnetic Roasting of Lean Ores

    Heretofore the basic concept behind most magnetic roasting processes has been the idea of heating iron ore to a temperature of 800° to 1100°F in a strong reducing atmosphere, preferably either carbon monoxide or hydrogen Temperatures under 800 °F were undesirable since excessive roasting time was required Temperatures over 1100 °F were avoided because of the danger of converting part of· The preliminary studies on magnetic roasting at the Mines Experiment Station were being conducted on a batch of Western Mesabi marginal ore designated as Batch No 11801 This ore was screened to a minus onehalf inch size, and some trouble was being experienced in attaining a complete magnetic roast of the ore under the conditions previously listedMagnetic Roasting of Marginal Iron OresIron ores Posted on 2009 2009 Beneficiation of a Colombian Oolitic Iron Ore Through Gravitational Separation Flotation Magnetic Roasting Magnetic Separation and Chemical Digestion Author :[PDF] Magnetic Roasting Of Iron Ore Download eBook Full

  • Characterization and technology of fast reducing roasting

    · The features of the techniques of fast reducing roasting (FRR) and conventional magnetic roasting, as well as tremendous demands of iron ores in iron and steel industry of China, were briefly described The test equipment suitable for FRR of finegrained materials was introduced Weakly magnetic materials with grain size of <030 mm were converted into strongly magnetic materials byHematite in the iron ore was reduced to magnetite through magnetic roasting at 800 °C for 60 min, and iron was enriched through magnetic separation However, an efficient separation between magnetite and quartz in the RRP800 °C was difficult to achieve because of the liberation issues, and the maximum Fe content in the concentrate only increased to 5761% In addition, the contents of PbComparing strategies for iron enrichment from Zn and PbMagnetic roasting Magnetic roasting involves controlled roasting of the ore to convert it into a magnetic form, thus enabling easy separation and processing in subsequent steps For example, controlled reduction of haematite (non magnetic Fe 2 O 3)Magnetic Separation Equipment For Iron Ore Haematite
