With the depletion of high grade iron ore, the removal of alumina containing minerals and phosphorous from low grade iron ore has received increasing attention in iron ore industry. The flotation behaviour of kaolinite was found to be opposite to that of quartz and special care has to be taken for the successful removal of the clay mineral.

AbstractKaolinite is a common gangue mineral in iron ore and sodium silicate has been used widely as a dispersant of silicate gangue minerals including kaolinite in various iron-ore flotation methods over a wide range of pH. Its actual dispersive effect on kaolinite under iron-ore flotation conditions has received very limited attention, however.
Mineralogical study revealed that Dilband iron ore is mainly composed of 46.27 % hematite, 17.41 % quartz 14.47 % calcite, 9.24 % chlinochlore, 10.5 % kaolinite, and 1.75 % fluorapatite minerals.

FESEM images indicated the morphological transformation of plate-like kaolinite for kaolinite nanotubes with a halloysite-like structure. Keywords: iron ore tailings, kaolinite, intercalation, nanotubes, halloysite. Resumo
The fine iron ore mostly contains goethite, kaolinite and other gangue material along with hematite mineral. And the sludge of these minerals became a complex ore. The low grade fines generated during crushing and screening, is scrubbed using screw scrubber or screw classifier to remove the below 100-µm size fractions material.
The iron ore slimes, which contain low iron content with high gangue minerals like kaolinite, gibbsite, and quartzite, cannot be used directly for iron production. The present study focuses on utilization of iron ore slimes without beneficiation by blending with high-grade fines for making iron ore pellets.

The low-grade iron ore generally contains goethite as the major iron phase mineral and kaolinite and other minerals as gangue minerals. During the beneficiation of low-grade iron ore, a lot of fines were generated during different unit operations. These fines report to the tailing pond for the settling of the particles.
