Abstract:
Ketoximes, processes for their preparation, compositions containing them, and a copper extraction process using the compositions. One process for the preparation of the ketoximes comprises the following steps: A) reacting a phenol with a monocarboxylic acid, monocarboxylic acid halide, or monocarboxylic acid anhydride in an inert organic solvent in the presence of an acid catalyst to esterify the phenol; B) removing any water of reaction produced in step A) either during step A) or in a separate step following step A); C) adding a Lewis acid to the resulting anhydrous reaction mixture; D) heating the reaction mixture from step C) to a reaction temperature sufficient to obtain a ketone by the Fries Rearrangement; E) maintaining the heated reaction mixture for a time period of from 2 to 8 hours at the reaction temperature; F) at a time of from half to three-quarters of said time period, adding to the heated reaction mixture additional aliphatic monocarboxylic acid, acid halide, or acid anhydride, optionally with additional Lewis acid, and continuing to maintain the heated reaction mixture at the reaction temperature for the remainder of said time period; G) isolating the ketone reaction product from the reaction mixture; and H) reacting hydroxylamine or a salt thereof with the ketone obtained in step G) to produce a ketoxime from said ketone.

Abstract:
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 R is a C linear or branched alkyl group, a C linear or branched alkenyl group, a C aryl group, a C aralkyl group, a halogen, OH or âOR wherein R is a C linear or branched alkyl group, a C linear or branched alkenyl group, a C aryl group, a C aralkyl group; R is hydrogen, or a C linear or branched alkyl or alkenyl group, a C aryl group or a C aralkyl group; R -R is hydrogen, halogen, a linear or branched C alkyl group, âOR wherein R is a C linear or branched alkyl group, a C linear or branched alkenyl group, a C aryl group, or a C 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 R -R 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.

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.

Abstract:
An improved process for the extraction of a metal from an aqueous ammoniacal solution comprising: (i) contacting the aqueous ammoniacal solution with an extraction reagent comprised of a water insoluble extractant for the metal, to provide an organic phase, now containing metal values, and an aqueous phase from which metal values have been extracted; (ii) contacting the organic phase with an aqueous stripping solution to provide an aqueous strip phase, now containing metal values, and an organic phase from which metal values have been stripped; and (iii) recovering the metal values from the aqueous stripping solution; the improvement wherein (a) the extraction reagent contains an ammonia antagonist having only hydrogen bond acceptor properties; (b) the stripping solution is an aqueous highly acidic solution; and (c) the organic phase is washed with a weakly acidic aqueous solution prior to stripping with the highly acidic aqueous stripping solution. The extractant is preferably an oxime extractant, either a ketoxime or an aldoxime. The preferred hydrocarbon solvent is kerosene and the preferred antagonist is 2,2,4-trimethylpentane-1,3-diol diisobutyrate.

Abstract:
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.

US Classification:
210638
Abstract:
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.
