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.

Collector composition

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 Ris C-Calkyl or alkenyl, which is linear or branched, Ris H, C-Calkyl, which is linear or branched, Ris —X—NH, H or C-Calkyl, which is linear or branched, and X is C-Calkylene, 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 Ris C-Calkyl, which is linear or branched, Ris H, Ris —X—NHand X is C-Calkylene, which is linear or branched, is disclosed.
