What is the role of depressant in froth floatation process Answer In the froth floatation process the role of the depressants is to separate two sulphide ores by selectively preventing one ore from forming froth For example to separate two sulphide ores ZnS and Pbs NaCN is used as a depressant which selectively allows PbS to come with Evaluation of graphite depressants in a poly metallic sulfide flotation Synthetic dyes are commonly used for graphite depression in poly metallic flotation zinc ZnS and other critical minerals such as silver cadmium In the zinc flotation sodium
