    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: The invention is directed to adhesive remover compositions and methods of their use. The adhesive remover compositions generally comprise a glycol ether solvent system comprising an aliphatic glycol ether, an aromatic glycol ether, a hydrophobic glycol ether, and a hydrophilic glycol ether, and a surfactant system. In further embodiment of the invention, the surfactant system may comprise three surfactants. In another aspect of the invention, the composition effectively removes medical adhesives from healthcare textiles. In a particular embodiment of the invention, the surfactant system may comprise one or more nonionic surfactants.
