    A process is described for the separation of copper values from an acidic aqueous solution thereof by liquid-liquid extraction with an extractant comprising an organic solvent and a dissolved hydroxy-oxime. The process utilizes a known hydroxy oxime of the general formula A- C(=NOH) - R, (I) in which R represents a hydrogen atom or an aliphatic group and A an aromatic group carrying as substituents a hydroxyl group at a ring carbon atom in a 2-position-the number 1 being assigned to the ring carbon atom to which the-C(=NOH)-R group is attached- and optionally an organic group D, and/or (2) a known 2-hydroxybenzophenone oxime substituted by a saturated or ethylenically unsaturated aliphatic group or groups or the corresponding ether group or groups in combination with (a) hydrocarbyl hydroxymethyl ketone oxime, (b) 2-hydroxyaldoxime in which the carbon atom carrying the hydroxyl group also carries two hydrocarbyl groups or one hydrocarbyl group and one hydrogen atom,(c) 2-hydroxycycloalkanone oxime in which the cycloaliphatic ring also carries one or more organic groups or aliphatic alpha-hydroxy-oxime of the general formula (II) in which R1, R2 and R3 each represent an organic group and R3 may also represent a hydrogen atom with the proviso that an aliphatic alpha-hydroxy-oxime of the general formula II is present only whenever a hydroxyoxime of the general formula I is also present. The process is particularly suitable for the separation of copper values from iron values.

    This invention relates to non-ferrous metallurgy, in particular copper hydrometallurgy. The known method of extraction of copper from acidic solutions using hydroxy-oxime of the general formula QJ, // - ° where X is H, -CH, -CH "- / P g - dissolved in an organic solvent, with 4–12 mol .% extractant - process accelerator. According to a known method of copper extraction, 2-hydroxybenzophen nonoxime with aliphatic alpha hydroxy oximes of the general formula RI is CC-RJ Rj where R, R / ,, R. g can be any organic radic, for example, aliphatic and alkylaryl rgschikly, Rg can also represent a hydrogen atom l3. However, this method does not have a high enough process speed. The purpose of the invention is to intensify the process. This goal is achieved by using an extractant selected from the group of oximes containing hydroxymethyl ketoxime, 2-hydroxyaloxime, 2-hydroxycycloalkanone oxime as an additive. Research has established that with this combination of oximes, when the hydroxymethylketone oxime has an alkyl group containing more than 5 carbon atoms, and is n-dodecylhydroxymethylketoxime, or hydroxymethyl ketoxime is alkylphenylhydroxymethyl ketoxime, or 2-hydroxyaloxime is alomeloxylel b) sym containing 8-20 carbon atoms, namely: 2-hydroxyalkanaloxime, 2-hexyl, 2-hydroxydecanaloxime, 2-hydroxy-2-pentylnonaloxime, or 2-hydroxycycloalkanone oxime contains It is an alkyl group attached to a cycloaliphatic ring, and is 2-hydroxy-2-methylcyclododecanoxime or 2-hydroxy-2,6,10-trimethylcyclododehanone oxime, the process proceeds much faster, thus increasing the selectivity of extraction with respect to iron.
    The extraction is carried out with the ratio of the organic phase to the aqueous from 1: 3 to 3: 1, the best results are obtained at 15-35 s, however, the process can be carried out within the specified interval at 0-15 ° C and 35-75 ° C. Hydrocarbons such as kerosene, toluene or xylene, as well as halogenated solvents, such as chloroform, 1, 2-dichloroethane, 1,2-dichloropropane and 2-chloroethylether, are used as solvent extractants.
    Some of the oximes used are synthesized, such as 2-alkyl-2-oxycyclododecanone-. an oxime in which 10 carbon atoms in the ring are unsubstituted, for example, 2-hydroxy-2-methylcyclododecanone oxime; 2,6,10-trialkyl-2-oxycyclododecanone-oxxy, in which three alkyl groups are the same and 8 carbon atoms in the ring are unsubstituted, for example, 2-hydroxy-2,6,10-trimethylcyclododecanone-rxim and 4-alkyl-.2 o-cyclic-hexanone-oximes, for example, 4-alkyl-2-hydroxycyclohexanone-oximes, in which the alkyl group has more than 3 carbon atoms, for example, as in 2-hydroxy-4-pentylcyclohexane.
    sanon oxime. The novel compounds are prepared by reacting the corresponding double-bond precursors with nitrosylsulfuric acid and then reacting the resulting 2-oximinoacidic sulfate with water. For example, 2-alkyl-2-oxycyclododecanone oxime, in which 10 carbon atoms of the ring are not substituted, is obtained by reacting the corresponding 2-alkyl cyclododecene with nitrosylsulfuric acid, followed by treatment of the resulting acidic 1-alkyl-2-oxy-amino-cyclododecyl sulfate with water, 2-hydroxy-2, b , 10-trimethylcyclododecanone oxime - by the interaction of 2,6,10-trimethyl-1-cyclododecene with nitrosylsulfuric acid and subsequent treatment of the resulting acidic 1,5,9-trimethyl-2-oxyminosulfate with water, etc.
    An example of the method.
    The initial acidic sulphate solution (pH 1.9) contains 63 mmol / l copper and 36 mmol / l iron (11).
    Extraction is carried out in a 250 ml separatory funnel with a stirrer. A kerosene fraction with a boiling range of 210-240 ° C is used as a solvent. 100 ml of the initial aqueous solution and 100 ml of organic. extractant is stirred in a funnel at 25 ° C with a speed of
    2000 rpm
    The results of the extraction experiments are shown in the table.
