Abstract: The invention relates to a method for manufacturing a concentrate enriched in iron mineral content from an ore, which contains an iron mineral and silicate, by a reverse flotation, which method comprises the step of adding a first amine to a prepared aqueous pulp of the ore and optionally one or more flotation auxiliaries to obtain an aqueous mixture, wherein the first amine (A) is a compound of formula I (I),a salt of a protonated compound of formula I and a first anion or a mixture thereof. A second amine, which is a compound of formula II (II), a salt of a protonated compound of formula II and a second anion or a mixture thereof, can be further added. Furthermore, a specific composition of the first amine (A) and the second amine (B) for a use as a flotation collector is described.
