The article reports the studies into surface wetting of sphalerite, chalcopyrite and pyrite after treatment in saltish solution and in artificial sea water with concentration of 2, 8 and 16‰. The collecting agents were potassium isopropyl xanthate and sodium isopropyl dithiophosphate (Aeroflot). The results show that depending on concentration of sea salt and collector as well as on collector type, the surface of sulfide minerals can either be hydrophilic or hydrophobic, which can influence flotation efficiency of such minerals in saltish and sea water.
