    Feb 19, 2019· 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 frothFor example, sodium cyanide is a depressant used for an ore containing Z n S and P b S N a C N forms a layer of the complex N a 2 [Z n (C N) 4 ] on the surface of Z n S and prevents it from forming a froth Thus, it acts as a depressant However, N a C N does not prevent P b S from forming froth and allows it to come with frothWhat is the role of depressant in froth floatation process?
