    Froth Flotation Process. The use of these reagents has been extended in recent years to three- stage selective flotation. For example, ores containing the sulphide minerals of lead, zinc, and iron, can be treated to yield three successive concentrates, wherein each class of minerals is recovered separately more or less uncontaminated by the others.

    The flotation reagents can be added in a feed-forward fashion based on the plant raw coal tonnage. Automatic feedback control of the flotation reagent addition rates has been lacking due to the unavailability of sensors for determining the quality of the froth cell tailings. Expensive nuclear-based sensors have been tried with limited success.

    Flotation Reagent. Flotation reagents have two important structural features: a functional group consisting of donor atoms or ligands, and a substituent group, which is hydrophobic consisting of alkyl aryl hydrocarbon chains in the case of collectors and frothers, or hydrophilic in the case of modifiers (except for inorganic modifiers, which comprise mainly inorganic bases and metal ions).

    As the froth gets deeper, the rate of froth removal reduces at a constant air addition rate. It is important to note that froth depth relationships are not linear in nature. Once a froth depth has been established for a particular flotation duty (i.e rougher, cleaner etc), changes are generally small and infrequent.
