Abstract: Disclosed herein are compositions and methods for lithium ore beneficiation. The methods and compositions are suitable for use in froth flotation of lithium ore sources. The methods include combining a lithium ore source, a water source, and a collector composition 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 a C10 to C28 hydroxycarboxylic acid, a surfactant, and a solvent. The collectors obtain high yield of lithium and excellent selectivity for lithium species in the froth flotation of lithium ores.

Abstract: Described herein is a method of adding one or more boronic acid functional compounds to a mineral ore to result in a treated mineral ore. Where the mineral ore is a bauxite ore, and the ore is subsequently processed according to the Bayer process to obtain alumina, adding a boronic acid functional compound to the bauxite ore or a Bayer product followed by processing the treated bauxite ore or treated Bayer product using one or more processes associated with the Bayer process results in an increased yield of alumina product, increased alumina content (purity) in the alumina product obtained, or both when compared to the same bauxite ore or Bayer product subjected to the same process(es) but in the absence of a boronic acid functional compound.

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.
