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.

FROTH FLOTATION : RECENT TRENDS Flotation of

2011-12-1  As regards other reagents used in sulphide flotation, depressants like sodium cyanide, ZnSO4, sodium meta bi-sulphite are common. Effectiveness of depressant also depends on concentration and selection of collectors. In case of cyanide as iron sulphide depressant there is a relationship between concentration of collector and cyanide ion present.
