    Abstract: Disclosed herein are compositions and methods for lithium ore beneficiation. The methods and compositions are suitable for use in flotation of lithium ore sources such as pegmatite, Zinnwaldite, Jadarite, or lithium mica. The methods include combining a lithium ore source, a water source, a collector, and optionally a frother to form a lithium beneficiation slurry; sparging the lithium beneficiation slurry; separating the sparged lithium beneficiation slurry to form a lithium beneficiary and a gangue; and collecting the lithium beneficiary, where the collector includes an oleic acid source, a hydroxycarboxylic acid, and a surfactant. The collectors obtain improved performance in terms of purity of lithium recovered from the ore, as a function of percent lithium recovery.

    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
