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.

Abstract Froth flotation is widely used for concentration of base metal sulphide minerals in complex ores. One of the major challenges faced by flotation of these ores is selection of the type of flotation reagents. In this study, the D-optimal experimental design method was applied to
Oct 16, 2017 Besides these physical aspects, the reagent scheme can also be changed to achieve the desired performance. The correct combination of all these factors for a specific ore provides the optimized concentration of minerals. Features of a column. Since columns do not have mechanical agitation, their energy consumption is optimal.
The study aimed to explore appropriate flotation reagents to recover copper minerals from a high content of slime and refractory oxidized copper ores.
