Three gravity separation methods have historically been used for iron ore namely (i) washing, (ii) jigging, and (iii) heavymedia separators Spirals and reichert cones are other two methods for gravity separation Wastes from gravity concentration are tailings made up of gangue in the form of coarse and fine grained particles and process water Simple washing of these low grade ores by scrubbing could not upgrade the iron content as evidenced from some laboratory studies However the utility of these ores in sinter or pellet making have urged many laboratories in India to undertake systematic studies for recovering iron values from these lowgrade oresEffective Beneficiation of Low Grade Iron Ore Through Beneficiation of lowgrade finegrained hematite ores becomes increasingly important due to rapid depletion of high quality iron ore resources However, fine particles, especially ultrafine particles, make efficient beneficiation of these ores more difficult Therefore, methods to reduce the influence of fine particles must be considered to 613Wei AusIMM the beneficiation of finely grained ores [28, 29] With these conventional methods and depending on the liberation particle size of the ore, significant amounts of fine iron are lost to the tailings [30] For this reason, all of these methods are only partly successful in the fine particle size range However, significant advancement is made in theOpen Access Recovery Improvement of Fine Iron Ore Characterisation of the iron ores and fines consisted of various methods including size analysis, chemical analysis XRD, EPMA study and microscopic analysis The details of the characterisation and possible beneficiation approaches are presented in the following sections rich variety of fine grained powdery ore and blue dust ore has to be (PDF) Beneficiation techniques for Iron ores from
