Role Of Depressant In Froth Flotation Process

What is the role of depressant in froth floatation process?

2019-2-19  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.

What is the role of depressant in froth floatation process

In froth floatation process,depressants are used to separate two sulphide ores by selective prevention of froth formation by one ore and allowing the other to form froth.

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 Na2[Zn(CN)4].4NaCN+ZnS → Na2[Zn(CN)4] + Na2S

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.
