Figure 2 Typical form of Grade/Recovery Curves for froth flotation 1.2 Hydrophobicity/hydrophilicity The basis of froth flotation is the difference in wettabilities of different minerals. Particles range from those that are easily wettable by water (hydrophilic) to those that are water repellent (hydrophobic).
