Moreover, the thermal treatment of the iron ore samples resulted in a higher yield due to the phase transformation of the iron oxide from goethite and hematite to magnetite. The Cumulative Fe grade of all the iron ore samples gradually decreased with the increase in magnetic intensity, which is shown in Fig. 8. Higher the magnetic intensity ...

Iron ore tailing/slime (-150 μm) is produced after scrubbing and wet screening of a low-grade iron ore. Tailing beneficiation of iron ore has been addressed either by flotation or wet high intensity high gradient separation. The present study aims to recover iron values from discarded slime containing assay ~56% Fe, ~6.5% SiO 2, and ~7.0% Al 2 O 3

In particular, for a fixed ore type ground to a specified particle size distribution, increasing the dosage of any given collector from clearly being underdosed to clearly being overdosed gives an increasing value of R with dosage but also a curve of K demonstrating a maximum as a function of collector dosage. This phenomenon is shown in Figure ...
