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

Froth flotationis the mainprocessused to separate lead-zinc minerals from each other as well as from gangue. It is effectively applied for the concentration of Pb-Zn ores, but technically, it differs from one deposit to another due to gangue changes, mineral association and liberation size. However there are three types of lead-zinc ores, …
