    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 (c) adding a collector composition comprising



    (i) an amidoamine, which contains a compound of formula I








    or a salt of a protonated compound of formula I and an anion, and



    (ii) an alkyl polyglycoside, which contains a compound of formula II








    wherein



    RAP is a linear or branched C6-C22 alkyl or a linear C6-C22 alkenyl,
    G1 is a monosaccharide residue having 5 or 6 carbon atoms,
    x is an average value from 1 to 10,

    to a prepared aqueous pulp of the ore and optionally one or more flotation auxiliary to obtain an aqueous mixture. Furthermore, the use of the collector composition as a flotation collector is described and the collector composition itself
