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 <img class="EMIRef" id="8406359a-2ef2-4152-bb23-dfd50a6c7bee-ia01" /> 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 <img class="EMIRef" id="8406359a-2ef2-4152-bb23-dfd50a6c7bee-ia02" /> wherein R<AP> is a linear or branched C6-C22 alkyl or a linear C6-C22 alkenyl, G<1> 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.
