Principle of froth flotation. The differences in physicochemical surface qualities of distinct minerals are used in froth flotation. Differences in surface qualities between the minerals inside the flotation pulp become obvious after reagent treatment, and for flotation to occur, an air bubble must be able to attach itself to a particle and raise it to the surface.

The next stage after froth flotation is the thickening stage. The froth is poured into large tanks called thickeners. The bubbles break and solids from the froth solution settle at the bottom of the tank. The solids are then filtered to remove excess water, which can be reused in processing additional batches of sulfide ore.

Flotation
