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;
(ii) an ethoxylate, which contains a compound of formula II






RE—O—(—CH2—CH2—O—)n—H  (II),



wherein RE is a linear or mono-branched aliphatic C10-C20 alkyl or a linear aliphatic C10-C20 alkenyl, and n is an integer from 1 to 12,

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 iron mineral content from an ore, which contains an iron mineral and silicate, by reverse flotation, which method comprises the step of (c) adding a compound of formula I wherein R1 is C9-C22 alkyl or alkenyl, which is linear or branched, R2 is H, C1-C4 alkyl, which is linear or branched, R3 is —X—NH2, H or C1-C4 alkyl, which is linear or branched, and X is C2-C4 alkylene, which is linear or branched, or a salt of a protonated compound of formula I and an anion, to a prepared aqueous pulp of the ore and optionally one or more flotation auxiliaries to obtain an aqueous mixture. Furthermore, a method for manufacturing a specific group of compounds of formula I, i.e. compounds of formula 1-X wherein R1 is C9-C15 alkyl, which is linear or branched, R2 is H, R3 is —X—NH2 and X is C2-C4 alkylene, which is linear or branched, is disclosed.
