Beneficiation of iron ore slimes - COnnecting REpositories

slimes are to be beneficiated to produce an acce-ptable grade of iron ore concentrate for utilisa-tion of iron making by adopting techniques such as microballing followed by sintering, IN RED, ERLED, PLASMAR ED, etc. substantial quantity of this beneficiated iron ore could be utilised usefully, and the pollution problem could also be reduced.
