The results show that the dispersant acts on the fine particle content of the iron ore by removing ultrafine particles that are adhered to the surface of coarse particles, making the ultrafine available to the medium.

The beneficiation of iron ore slimes by selective flocculation was studied. Polyacrylamide (PAM) and guar gum were used as flocculant, along with sodium hexametaphosphate (SHMP) as a dispersant.

The presence of calcium and magnesium is particularly detrimental to kaolinite removal from iron ore[32]. For dispersant-kaolinite interactions, it was found that sodium silicate, a standard dispersant widely used in iron ore flotation for silicate

The presence of calcium and magnesium is particularly detrimental to kaolinite removal from iron ore [32]. For dispersant-kaolinite interactions, it was found that sodium silicate, a standard dispersant widely used in iron ore flotation for silicate gangue minerals, is inadequate to disperse kaolinite [35].

Kumar and Mandre (2016) evaluated the selective flocculation to treat iron ores slimes applying polyacrylamine and guar gum as a flocculant and sodium hexametaphosphate as a dispersant.

Similarly, sodium silicate, a good dispersant for silicates present in iron ore does not disperse any kaolinite (Ma et al., 2009a). Taking into consideration all the above facts, we aimed to seek a thorough understanding of the difference in the flotation response of a quartz rich and an alumina rich ore in a comprehensive manner.

iron ore differently. Sodium silicate caused little to no dispersion in the presence of 20 ppm calcium. All of the phosphate based dispersants effectively re-dispersed the ore in the presence of 20 ppm calcium. EDTA caused further flocculation of the ore in the presence of 20 ppm calcium. It has been concluded
