ABSTRACT:
A process for recovery of zinc values from aqueous ammoniacal solutions employing certain alkylsalicylaldoximes or acetophenoximes as the extractant. The method also provides a means for separation of the zinc and copper values present in the aqueous ammoniacal solution. The zinc and copper values are separately recovered from the organic phase by pH controlled stripping.
