摘要： Novel modified and improved beta-diketones and their use in the extraction of copper from aqueous ammoniacal solutions containing copper values, resulting from commercial processes, including, but not limited to, leaching of copper containing ores, such as sulfidic ores, or concentrates resulting from flotation of such sulfidic ores. The novel diketones are those highly sterically hindered, which may be represented by the formula I or II: ##STR1## The preferred beta-diketones of Formula [II] are selected from the group consisting of neo-alkyl beta-diketones, such as, 1-phenyl-3-neoalkyl-1,3 propanedione in which the neoalkyl group is selected from neohexyl, neoheptyl, neooctyl, neononyl, or neodecyl.

摘要： Copper is preferentially extracted from iron in an aqueous feedstock solution containing dissolved copper and iron values by contacting the feedstock solution with a water-immiscible organic solution comprised of a hydrocarbon solvent and a compound of the formula I wherein R5 is a C1-22 linear or branched alkyl group, a C2-22 linear or branched alkenyl group, a C6 aryl group, a C7-22 aralkyl group, a halogen, OH or —OR6 wherein R6 is a C1-22 linear or branched alkyl group, a C2-22 linear or branched alkenyl group, a C6 aryl group, a C7-22 aralkyl group; R1 is hydrogen, or a C1-22 linear or branched alkyl or alkenyl group, a C6 aryl group or a C7-22 aralkyl group; R2-R4 is hydrogen, halogen, a linear or branched C6-12 alkyl group, —OR6 wherein R6 is a C1-22 linear or branched alkyl group, a C2-22 linear or branched alkenyl group, a C6 aryl group, or a C7-22 aralkyl group to form an aqueous phase comprised of iron and an organic phase comprised of the hydrocarbon solvent and a copper-extractant complex wherein the copper-extractant complex is soluble in the hydrocarbon solvent. The R2-R5 groups are chosen so that the copper-extractant complex is soluble in the hydrocarbon solvent. After the extraction stage is completed and the organic and aqueous phases separate, the organic phase is substantially free of iron and/or an iron-extractant complex.

摘要： The preparation of concentrated solutions of oxime metal extractants, such as aldoximes and ketoximes, or mixtures of aldoxime and ketoxime, and the use thereof in formulating or preparing extraction reagent compositions for use in an extractant organic phase in a process of extracting metals from aqueous solutions containing metal values; and in particular, to concentrates which are solutions of individual ketoxime or aldoxime or mixtures of water-insoluble hydroxy aldoximes and ketoximes, in varying ratios by weight of 1:100 aldoxime to ketoxime, or conversely, 100:1 ketoxime to aldoxime, in water-immiscible hydrocarbon solvents or equilibrium modifiers. The invention also provides for maintaining stability of concentrates determined by accelerating rate calorimetry to define the ranges of oxime concentration and volume whereby the concentrate will be a stable, flowable, pourable and pumpable concentrate which can be safely stored long term. The extraction compositions may also optionally contain equilibrium modifiers or kinetic additives.

摘要： Improvement in the process of extracting metals, particularly copper, from aqueous ammoniacal solutions with beta-diketone extractants dissolved in a water immiscible hydrocarbon diluent, such as a kerosene, in which the improvement comprises application of a voltage potential across the interface of the aqueous and organic layers of an extraction circuit with an electrostatic coalescer, and maintaining the voltage potential until the layers have been separated, to control entrainment of the aqueous layer into the organic layer, thereby significantly reducing metal production cost and providing improved metal quality by minimizing ammonia entrapment and carry over to the aqueous stripping solution from which the metal is recovered, typically by electrowinning of the aqueous acid strip solution.
