FROTH FLOTATION : RECENT TRENDS Flotation of Sulphide Ores - HZL Experience

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.
