Nov 22, 2019 · For example, sodium cyanide is a depressant used for an ore containing ZnS and PbS . NaCN forms a layer of the complex Na2[Zn(CN)4] on the surface of ZnS and prevents it from forming a froth. Thus, it acts as a depressant. However, NaCN does not prevent PbS from forming froth and allows it to come with froth.

What is the role of depressant in froth floatation process?

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 froth, but prevents ZnS from coming to froth.
