• Copper–molybdenum ores flotation in sea water

    2013-11-1 · Laboratory rougher flotation tests were conducted with two samples of Cu–Mo ores in fresh water and in sea water as a function of pH. In both cases Cu recoveries were slightly lower in sea water than in fresh water for a wide range of pH (pH 7–12). Flotation of molybdenite was however strongly depressed in sea water at pH higher than 9.5.Flotation separation of copper–molybdenum sulfides using,2015-11-1 · 1. Introduction. The selective separation of copper–molybdenum sulfide minerals by flotation mostly relies on the use of various depressants. Sodium hydrosulfide, sodium sulfide, cyanide and Noke’s reagent (thiophosphorus or thioarsenic compounds) are routinely used as the selective depressants of chalcopyrite (Bulatovic, 2007, Pearse, 2005, Prasad, 1992, Yin et al.,
