A second factor that forces the mining industry to incorporate the concentration stages into the production process, is the technological advances in the steel industry that have had a major impact on iron ore demand, especially regarding the particle characteristics and uniformity (e.g. specific particle size, and iron content).

Froth flotation process and its application

The metal-sulfide ore is hydrophilic in nature. So the hydrophilic part of the surfactant will be towards the ore and the hydrophobic part will be away from it (figure 5). Hyd ro ph il c a t Hydrophobic part + Ore Figure 5: Schematic representation of ore encapsulation Thus the ore becomes hydrophobic in nature and water-repellant as well.
