Abstract
The present invention relates to a collector composition for the beneficiation of lithium silicates and magnesium silicates from an ore comprising different silicate minerals, their use in flotation processes and a method for the beneficiation of lithium silicates- and magnesium silicates-containing minerals using said collector composition.
Claims21
A method comprising beneficiating lithium silicate minerals and magnesium silicate minerals from an ore comprising different silicate minerals, utilizing a collector composition, wherein the collector composition comprises:
- A. at least one component (A) selected from compounds of formula (I) and salts thereof,
- G1-C(═O)—NR—CH(R1)—C(═O)—OH formula (I),
- wherein G1 is a linear or branched, substituted or unsubstituted, saturated or unsaturated C6-C30 hydrocarbon chain;
- and
- R and R1 independent of each other are selected from the group consisting of hydrogen and linear or branched, substituted or unsubstituted, saturated or unsaturated C1-C30 hydrocarbon chain;
- and
- B. at least one component (B) selected from the group consisting of saturated or unsaturated alcohols containing at least 10 carbon atoms (B1) and an ester containing at least 10 carbon atoms (B2) derived from a mono-, di- or tri-functional carboxylic acid.
