Abstract: 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.

Abstract: A low viscosity water insoluble extraction reagent composition according to the invention is comprised of: (a) an extractant selected from the group consisting of an aldoxime, a ketoxime, or a combination thereof; (b) an equilibrium modifier having a Brookfield viscosity of equal to or less than about 5 centapoise at 25° C. and a flash point equal to or greater than about 141° F. wherein the molar ratio of modifier to extractant is from about 0.05 to about 2.0 so as to provide a net copper transfer greater than that achieved in the absence of modifier. Such low viscosity extractants afford higher recoveries of copper, permit reduced equipment size such as smaller mixers and settlers and the use of reduced amounts of less overall organic inventory.

Abstract: A process for removing and recovering ammonia from the organic extraction phase in a metal liquid-liquid extraction process in which at least one ammoniacal aqueous solution (either a leach feed solution containing the metal to be extracted or an aqueous stripping solution employed to strip the metal values from the organic phase) is contacted with the organic phase which comprises a water insoluble, water immiscible hydrocarbon solvent solution of a water insoluble organic extractant for the metal.

Abstract: The recovery of nickel from aqueous ammoniacal solutions containing nickel values by extraction of the nickel values therefrom with an organic solution containing an oxime extractant and an equilibrium modifier followed by stripping of the nickel values from the organic solution by a concentrated aqueous ammoniacal solution from which the nickel can then be recovered. The use of the equilibrium modifier and the concentrated ammonia stripping solution provides advantages in that (1) there is an increase in the nickel transfer of the reagent, (2) the strip solution can be built to a higher nickel concentration giving a lower volume nickel containing solution for further processing and (3) a lesser number of stripping stages are required.

Abstract: A process for recovery of metal values from a mixed metal chloride containing leach solution by contacting the leach solution with a water immiscible solution of a complexing agent selective for the neutral chloride of the metal to be recovered and a chelating agent having affinity for the cation of the metal to be recovered. The chloride ion is washed from the water immiscible solution by contact with a chloride ion washing solution. The water immiscible solution containing the chelated metal ion is stripped with an aqueous stripping solution. The metal is recovered from the aqueous stripping solution.

Abstract: An improvement is disclosed in the solvent extraction process for recovering metal values, i.e. copper, from aqueous solutions, particularly aqueous solutions, containing copper and iron which may also include chloride, and more particularly to an improvement which provides for increased copper to iron ratios in the loaded organic extractant phase. The improvement comprises washing the loaded organic extractant phase prior to stripping of the copper values therefrom with an aqueous acidic scrub solution containing at least a portion of electrolyte.
