Abstract
Use of a mixture of a C9 alkylsalicylaldoxime and a ketoxime as an extractant in a water-immiscible organic solvent solution in a metal extraction circuit to enhance the transfer of iron values to a dilute acid wash solution when the metal loaded organic solvent/extractant solution is washed with the dilute acid wash solution.
