    Tested with six pentlandite-bearing sulfide ores, a similar nickel leaching efficiency was achieved at both pH 2.00 and 3.00. Unlike chalcopyrite and pyrite, the bioleaching of nickel from pentlandite could be achieved with a lower concentration of Fe 3+ and higher pH value. Most pentlandite-bearing ores are associated with magnesium-bearing .

    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. In this .
