Zusammenfassung:	In a flotation separation process wherein oxide copper ores in subdivided form are concentrated by slurrying raw ores containing oxide copper ores in an aqueous solution of a flotation reagent followed by generating gas bubbles in the slurry to float the oxide copper ores and recovering the concentrated oxide copper ores from the surface of the slurry, the improvement therein which comprises employing as the flotation reagent a condensation reaction product derived from A. a substituted phenol of the formula WHEREIN R is an alkyl group having 8 to 12 carbon atoms and R' is H or a (CH2CH2O)xH radical where x is an integer of 1 to 3, B. an alkylene polyamine of the formula H(HN-9 CH2CH2)yNH2 wherein y is an integer of 2 to 6, and C. formaldehyde.
