    What Is The Role Of Depressant In Froth Floatation Process

    The role of depressant in froth floatation process is to prevent certain type of materials from forming the froth with bubbles. 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. This happens because NaCN reacts with ZnS to form Na2Zn(CN)4.4NaCNZnS Na2Zn(CN)4 Na2S

  • What is the role of depressant in froth floatation process

    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.
