 — For example: sodium cyanide can be used as a depressant in the separation of zinc sulphide ore (ZnS) and lead sulphide ore (PbS). Sodium cyanide forms a layer of zinc complex, Na 2 [Zn(CN) 4] on the surface of ZnS and therefore prevents it from forming the froth. Therefore, it acts as a depressant. 4 NaCN + ZnS —–> Na 2 [Zn(Cn) 4] + Na 2 S
