  • Write The Principle Behind The Froth Floatation Pr Topprm

    Froth floatation process is based on the principle that the metallic sulphide particles of ore are preferentially wetted by oil and the gangue particles by water.Collectors attach themselves by polar groups to grains of minerals which then become water repellent and thus, pass on into the froth.Examples are ethyl xanthate and potassium ethyl xanthate.

  • 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.
