  • BENEFICIATION OF PHOSPHATE FROM PHOSPHATE CONTAINING ORES
    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.
