control in iron ore flotation circuits and the level of ionic strength in iron ore flotation pulp. 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

Froth Flotation of Iron Ores

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].

Role of silica and alumina content in the flotation of iron ...

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.

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
