Low grade Iron Ore Beneficiation and the Process of Sep 25, 2018 The reasons for choosing jigging for the iron ore beneficiation over other processes include (i) relatively easy separation, (ii) beneficial trade-off between operating cost and reduced yield relative to dense medium processes, (iii) ability to treat ores requiring cut densities higher than a density of 4.0, and (iv.
Sep 25, 2018 Low grade Iron Ore Beneficiation and the Process of Jigging Iron ore resources are getting consumed at an accelerated rate because of the growth in the production of iron and steel. Due to this reason the availability of high grade iron ore is reducing and the supply of high grade iron ore to iron and steel plants is declining sharply.
The R D efforts undertaken at NML-Madras Centre, India in this direction have been highlighted. Beneficiation of iron ores in general and column flotation in particular are highlighted in this paper. This would also mitigate the environmental problem created by the dumping of huge quantities of low and medium grade iron orefines.
Two fine low-grade iron ores were used in this series of tests. The first ore consisted of an ultrafine Fe ore tailings sample with a D50 of 20 m and the second sample of an itabirite iron ore sample with a D50 of 60 m. Both samples present challenges during their beneficiation and cannot be.
