A review of froth flotation control
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 a dynamic situation …

Explaining the Process of Froth Flotation
The flotation process for the concentration of ores is a method by means of which one or more of the minerals in the ore (usually the valuable ones) are picked up by means of a liquid film and floated at the surface of a mass of fluid pulp. Here they are separated from the other minerals, which remain immersed in the body of the pulp. In general, the minerals which …

Froth Flotation: Factors affecting, Advantages, Disadvantage
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.

This branch of chemicals will prepare the mineral surface so other reagents will be able to collect the metal. For Conditioners and Modifiers, it may be simply cleaning the surface of the particles, as in the case of removing oxidization, or it may be a chemical that these are the chemicals that bind the mineral to the air bubble to be lifted away from the waste.
