all sulfide minerals are treated by froth flotation, as well as many oxide minerals and industrial minerals. In this process, mineral particles that have an affinity for air, known as hydrophobic particles, selectively attach to air bubbles and are recovered in the froth at the surface of the flotation machine.

The two higher tiers of flotation control are advanced flotation control (AFC) and optimising flotation control (OFC). AFC involves the rejection of the effects from input disturbances to the process (e.g. a change in feed grade) and maintaining performance parameters — grade and recovery (although care should be taken when defining recovery; in …
