Iron ore slime from Bailadila region after beneficiation were taken for the pelletization studies. The Blain number (Specific surface area) of iron ore slime was 821 cm2/g. Initially, the iron ore slimes received were of inferior quality with 62.70% Fe(T) and SiO 2 and Al 2O 3 content were 7.65% and 1.75%, respectively. The slime sample

This chapter introduces the principle of how low-grade iron ores are upgraded to high quality iron ore concentrates by magnetic separation. ... the magnetic products from the LIMS and SLon magnetic separators are fed to the secondary ball mill system, ground to about 80% −75 micron particle size, and finally treated by secondary drum LIMS and ...

In the MEBIOS method, by arranging green balls, the iron ore that is thickly granulation-treated to large sizes of about 5–15 mm (hereinafter referred to as GB), in the conventional material layer

the iron grade changes in different size fractions. As it appears from Fig. 5, for size fractions of (–2000 + 300) micron, (–300 + 37) micron, and (–37) micron, iron grade equals to 44, 48 and 40%, respectively. A significant drop in iron grade for size fraction smaller than 37 micron implies the fact that de-sliming stage
