    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

    Abstract: Described herein are methods for manufacturing a concentrate enriched in iron mineral content from an ore, which contains an iron mineral and silicate, by a reverse flotation. The method includes adding a first amine to a prepared aqueous pulp of the ore and optionally one or more flotation auxiliaries to obtain an aqueous mixture. The first amine (A) may be a compound of formula 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




    a salt of a protonated compound of formula II and a second anion or a mixture thereof, can be further added. Further described herein are specific compositions of the first amine (A) and the second amine (B) for a use as a flotation collector.

    Abstract: The invention relates to a method for manufacturing a concentrate enriched in a phosphate mineral content from an ore, which contains a phosphate mineral and a non-phosphate mineral, by a flotation, which method comprises the step of adding a surfactant system comprising (A) a fatty acid, (B) a blend of ethoxylated and non-ethoxylated alcohols, which is obtainable by blending (i) a reaction product of a first C12-C16 aliphatic alcohol having an average degree of branching of 1.9 to 3.5 and 10 to 20 equivalents of ethylene oxide, and (ii) a second C12-C16 aliphatic alcohol having an average degree of branching of 1.9 to 3.5, wherein the amount of (i) is 80 to 95 wt. % and the amount of (ii) is 5 to 20 wt. % and wt. % is based on the overall weight of the mixture of ethoxylated and non-ethoxylated alcohols, to a prepared aqueous pulp of the ore and optionally one or more flotation auxiliaries to obtain an aqueous mixture. Furthermore, a use of the surfactant system as flotation collector is disclosed.
