What is the role of depressant in froth floatation process?

Depressants prevent certain types of particles from forming froth with bubbles. Due to this, we can separate two sulphide ores. For example, sodium cyanide is a depressant used for an ore containing Z nS and P bS. N aC N forms a layer of the complex N a2. ] on the surface of Z nS and prevents it from forming a froth. Thus, it acts as a depressant.
