  • Flotation Froth - an overview | ScienceDirect Topics

    Froth flotation technology has made substantial progress over the last fifty years. Coal is a solid combustible material and exists in the ground along with impurities. Coal, being composed of carbon elements, is hydrophobic in nature and thus is a good candidate for the froth flotation technique.

  • What is the role of depressant in froth floatation process?

    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.
