Abstract—The flotation of impregnated copper-nickel ores is studied using humate agents as depressors, which are obtained from oxidized brown coal by extraction with alkaline reagents. The effect of the humate agents on the flotation of some iron-bearing minerals (pyrite, pyrrhotine, chalcopyrite) among the sulfide ores, as well as the sorption of humates with minerals, are studied. The humate agents are found to have a depressing effect on both nonmetallic minerals and sulfides.
