    Dual effects of sodium sulfide on the flotation behavior

    Abstract. This study explores the flotation behavior of chalcopyrite in the presence of different concentrations of sodium sulfide (Na 2 S183;9H 2 O) at pH 12 under controlled potential conditions. It was observed that the flotation of chalcopyrite is not depressed completely when the pulp potential is low, even at high concentrations of sodium sulfide,
