  • Flotation separation of coppermolybdenum sulfides using

    The selective separation of coppermolybdenum sulfide minerals by flotation mostly relies on the use of various depressants. Sodium hydrosulfide, sodium sulfide, cyanide and Nokes reagent (thiophosphorus or thioarsenic compounds) are routinely used as the selective depressants of chalcopyrite ( Bulatovic, 2007 , Pearse, 2005 , Prasad, 1992 , Yin et al., 2010 ), the main copper sulfide mineral.
