The use of froth in flotation is twofold. First, froth is used to convey the mineral-laden bubbles from the froth–pulp interface to the concentrate launder. Second, froth is used to remove entrained hydrophilic particles by the gravity drainage of water back to the pulp (Figure 13). The froth cleaning process can be improved by spraying (wash ...

1 Froth Flotation – Fundamental Principles

2009-8-27 · 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). If a mixture of hydrophobic and hydrophilic particles are suspended in water, and air is bubbled through the suspension, then the hydrophobic particles will tend to attach to the air bubbles
