  • Publication number: 20220212204
    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.

  • Patent number: 11072840
    Abstract: The present invention relates to the use of hydrophobically associative copolymers as binders for pelletizing metal containing ores such as iron containing ores. The copolymers comprise monomer units derived from at least one hydrophobically as sociative monomer, preferably at least one unsaturated hydrophobically associating monomer.

  • Publication number: 20210197211
    Abstract: The present invention relates to a collector composition for beneficiation of phosphates from phosphate containing ores comprising at least one component A, at least one component B, and at least one component C, wherein the component A comprises unsaturated fatty acids having 12 to 22 carbon atoms, the component B comprises alkoxylated branched alcohols as non-ionic surfactant which comprise two different types of alkoxy moieties, and the component C comprises sulfur-containing surfactants. The present invention further relates to the use of said collector composition in flotation processes, and to a method for beneficiation of phosphates using said collector composition.
