  • Copper activation option for a pentlandite–pyrrhotite

    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 pentlandite–pyrrhotite–chalcopyrite 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.
