Advantages of iron ore slime beneficiation

a comparative study on characterisation and processing ofearlier work indicates that beneficiation of iron ore slime is not difficult, but the beneficiation of iron ore slime containing very low iron content and very high alumina content is difficult. also it is difficult to know the characteristic properties of the particles where most of the population is below 50 micron.recovery of iron bearing minerals from beneficiation plantto identify and establish beneficiation techniques for slime, a comprehensive research work was carried out on beneficiation plant 2 thickener underflow (tailing). iron ore slimes (45 micron ~80.0%) generated at beneficiation plant 2 assaying 46.7% fe, 10.82% sio2, and 4.58% al2o3 have been subjected to various beneficiation studies like cyclone, wet high intensity magnetic separator and irjetreprocessing of iron ore beneficiation plantduring the two slime samples from tailing dams of iron ore preparation of ore as a feed to blast furnace a significant beneficiation plants of m/s bmm ispat ltd. danapur and amount of slimes (0.050 mm ) and non magnetic tails are m/s jswl, vaddu, spread across bellary district were being generated.utilization of iron ore slime and bottom ash an overviewjan 01, · the promising areas for utilization of iron ore slime and bottom ash are the making of bricks (constructional, insulation), use as bed filter materials, and ferro / master alloys' production as a part of metal recovery using smelting reduction process.
