Abstract (en)
[origin: DE4133063A1] Described is a method of producing iron-ore concentrates by the flotation washing of iron ore using as the collector mixtures containing (a) at least one ether amine of the formula (I): R<1>O-[CnH2n]y-NH-[CmH2m-NH]xH, in which R<1> is a straight-chain or branched-chain aliphatic hydrocarbon group with 6 to 22 carbon atoms and 0, 1, 2 or 3 double bonds; n and m, independently of each other, are the numbers 1, 2 or 3; x is 0 or the number 1, 2 or 3; and y is 2 or 3; and (b) at least one other anionic and/or non-ionic collector.
