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.
