Zusammenfassung:	PCT No. PCT/EP92/02224 Sec. 371 Date Apr. 4, 1994 Sec. 102(e) Date Apr. 4, 1994 PCT Filed Sep. 25, 1992 PCT Pub. No. WO83/06935 PCT Pub. Date Apr. 15, 1993Iron ore concentrates can be obtained by the flotation of iron ores providing mixtures containing at least one ether canine of formula (I):R1O-(CnH2n)y-NH-(CmH2m-NH)xH,in which R1 is a linear or branched chain aliphatic hydrocarbon moiety having 6 to 22 carbon atoms and 0, 1, 2 or 3 double bonds; n and m independently of one another represent the number 1, 2 or 3; x=0 or the number 1, 2 or 3; and y=2 or 3, and at least one other anionic and/or nonionic collector.
