What is the role of depressant in froth floatation

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.

Flotation Kinetics an overview ScienceDirect Topics

In a traditional flotation cell, high speed impeller agitation is required to keep particles in suspension. Collectors such as xanthate salts related sulphur-based ligands and nonpolar oils (diesel and kerosene) are usually used to make valuable minerals hydrophobic while depressors are used sometimes to render gangue particles hydrophilic.
