Abstract: Metal contaminants may be problematic in a number of industries, particularly in the mining industry. Fines production and dust control may be similarly problematic in many industries, including the mining industry. Reaction products formed from a saccharide polymer and diallyldimethylammonium chloride (DADMAC) under room temperature to heating conditions in the presence of a hydroxide base or a radical initiator may be effective for promoting removal of metal contaminants from clay-containing substances, such as through froth flotation. The reaction products may also be effective for mitigating fines production and providing dust control by forming a coating upon a plurality of particulates.

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.

Abstract: One or more surfactants and one or more adjuvant gases in the hydrometallurgical and pyrometallurgical processes, which are added thereto in the state of nanobubbles and microbubbles, both the gases used and the nanobubbles and the microbubbles thereof, are in a variable proportion depending on the physicochemical requirements of each of the stages of the process where it is applied. The nanobubbles and microbubbles, of the proposed composition, make it possible to significantly increase the physicochemical properties of these gases such as: flotation speed, oxidizing power, reducing power, contact area provided and coalescence speed.

Abstract: The present application relates to a concentration process of iron minerals from ultrafine tailings (slimes) from iron ore processing through reverse flotation with pH between 8.5 and 10.5 with the addition of amide-amine type collector, or further a mixture thereof with traditional cationic collectors (amines), in the absence of any depressant, alternatively including a step of high field magnetic concentration, which allows to obtain a concentrate with iron content higher than 66% and contents of SiO2+Al2O3 below 4%.

Abstract: Improved sparge compositions for froth flotation separation, methods of using them, and uses thereof are described. The compositions are suitably used in the froth flotation of particulate material containing ultrafine particles, and are well suited to the froth flotation separation of finely comminuted poor (low-grade) ores. The sparge compositions comprise functionalized silicone containing functionality that is tailored to the chemical nature of a beneficiary or a gangue in the ore. Sparging of the compositions effects improved recoveries and purities of beneficiaries. Sparge compositions and functionalized silicones suitable for the froth flotation of iron ores containing silica and/or silicate impurities are described. Sparge compositions and functionalized silicones suitable for the froth flotation of ores containing sulfur compounds such as sulfides are also disclosed.
