    Abstract: The invention relates to a process for enriching an iron mineral from a silicate containing iron ore by inverse flotation comprising the addition of a collector or collector composition comprising at least one of the compounds of formulae RO—X—NH2 (Ia); RO—X—NH3+Y− (Ib); RO—X—NH—Z—NH2 (IIa); and RO—X—NH—Z—NH3+Y− (IIb), in which X is a linear or branched aliphatic alkylene group containing 2 to 6 carbon atoms; Z is a linear or branched aliphatic alkylene group containing 2 to 6 carbon atoms; Y− is an anion; and R is an aliphatic group of the formula (I) C5H11CH(C3H7)CH2— (I) wherein the C5H11 moeity of the aliphatic group of the formula (I) comprises 70 to 99% by weight n-C5H11—, and 1 to 30% by weight C2H5CH(CH3)CH2— and/or CH3CH(CH3)CH2CH2—. RO—X—NH2  (Ia) RO—X—NH3+Y−  (Ib) RO—X—NH—Z—NH2  (IIa) RO—X—NH—Z—NH3+Y−  (IIb) C5H11CH(C3H7)CH2—  (I)
