Methods suitable for purification of lithium ore sources such as spodumene-bearing pegmatite, petalite, Zinnwaldite, Jadarite, or lithium mica include combining a lithium ore source, a water source, a collector composition, and optionally a frothing agent 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 composition includes a fatty acid source, a sulfonated fatty acid source, and a fatty acid adduct of succinic anhydride. The collectors obtain improved performance in terms of reduced organic content, increased lithium content and decreased iron content. Additionally, in some cases the collectors obtain the ability to exclude addition of a separate frothing agent during the beneficiation.
A collector composition comprising:
A method of froth flotation comprising steps (I) or steps (II):
