Composition of oxime and hydroxy-ester for the solvent extraction of metals |
abstract |
A solvent extraction composition is provided which comprises one or more orthohydroxyarylaldoximes or orthohydroxyarylketoximes and one or more esters substituted with a hydroxyl group, and preferably a water immiscible organic solvent. The orthohydroxyarylaldoximes, or orthohydroxyarylketoximes commonly have Formula (1), wherein R1 is hydrogen or a hydrocarbyl group, and R2 is an ortho-hydroxyaryl group; and the esters substituted with a hydroxyl group are of Formula (2), wherein one of R7 or R8 is a substituted hydrocarbyl group with at least one hydroxyl group and the other is an optionally substituted hydrocarbyl group. Preferred orthohydroxyarylaldoximes are 5-(C¿9? to C14 alkyl)-2-hydroxybenzaldoximes and preferred orthohydroxyarylketoximes are 5-(C9 to C14 alkyl)-2-hydroxyacetophenone oximes. Preferred esters substituted with a hydroxy group are highly-branched alkyl esters comprising from 5 to 51 carbon atoms, wherein the hydroxy group resides on R?8¿. Processes for the extraction of metal values from aqueous acidic and ammoniacal solutions are also provided. |
