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 layer. Particles that are retained in the froth are recovered at the lip of the froth weir at the edge of the flotation cell. The recovery of the froth is accomplished by the natural mobility of the froth which causes it to flow over the weir and the recovery is sometimes assisted by mechanical paddles.
