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： 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： Toxic cyanide and anionic metal species are removed from aqueous alkaline solutions by contacting the aqueous alkaline solutions with an extractant compound which is capable of being protonated at a pH of 9 or above. Whereby the anionic metal species is extracted from the aqueous alkaline solution, subsequently stripping the metal values from the extractant and recovering the metal species, preferably by electrowinning. The process is useful in a flotation process in which a recycled aqueous process stream is employed in that the toxic cyanide ion and anionic metal species are removed prior to recycling of the aqueous process stream for flotation.

摘要： A game for a number of players comprises providing a deck of cards having fifty-one cards. The deck includes three jokers in combination with forty-eight cards organized in four suits, each suit having in six pairs of cards of the same type, wherein five of the types are sequential while the sixth type is not sequential with the other five. Each player places a first wager to participate in the wagering game. Each player is dealt two cards while a hole card is dealt for the table. All cards are dealt face down. Each player is given the chance to double down the first wager with a second wager. A hand is provided for each player with each hand comprising the hole card and the two cards each player was dealt. The first and second wagers are resolved based on said hand, wherein if a player's hand comprises a predetermined arrangement of cards, that player wins a corresponding preselected amount.
