Abstract
A solvent extraction composition that is particularly useful for the extraction of metals from a solution containing the metals. The solvent extraction composition includes an orthohydroxyaryloxime extractant, at least one water immiscible organic solvent, and an effective amount of a substantially water insoluble equilibrium modifier. The equilibrium modifier includes at least one of an aliphatic, aromatic or araliphatic compound comprising three or more ester functional groups. A method for the solvent extraction of a metal such as copper from an aqueous solution using the solvent extraction composition is also provided.
