Flotation Reagent - an overview ScienceDirect Topics

In froth flotation, the frother merely provides a froth phase with certain basic properties which get modified by several factors. Thus, the overall froth-phase properties are determined by the type and amount of all the three flotation reagents (viz. collectors, modifiers, and frothers), and by other chemical and physical factors; this is quite evident in any operating plant.
