1 Classification of Flotation Reagents. Modern classification of flotation reagents is based on the function of a particular reagent. On this basis, reagents are divided into collectors, frothers, regulators, and depressants. Collectors are a fairly large group of organic chemical compounds, which differ in chemical composition and function.
