But the total yield was 73.80% along with high tails Fe 58.67%. In this case study, it was clearly observed that the de-sliming cyclone overflow ...

A typical high-alumina containing iron ore slime from the eastern Indian sector containing 58.13% Fe, 6.48% SiO 2, 4.9 % Al 2 O 3 and 5.35% LOI, have been evaluated to find out whether grinding of the slimes will be beneficial or not for upgrading the slime to generate pellet-grade concentrate with >64% Fe.

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) physical characteristics of ...

The beneficiation of iron ore deposits to yield haematite and magnetite concentrates for steel making processes typically require the use of one or a combination of wet processing techniques based on gravity, magnetic or froth flotation processes.
