may 30, 2016 different sulphide ores respond differently in the prospect of copper activation to thiols for froth flotation. with the bcl selebi-phikwe ore body, co-occur and there is the constraint of fine pentlandite dissemination in the pyrrhotite, so that liberation is limited. In the presence of pentlandite, pyrrhotite can even be galvanically depressed.
