METHODS OF METAL EXTRACTION FROM AMMONIACAL SOLUTIONS USING OXIMES

摘要

Provided are methods using ketoximes and/or aldoximes, including 3-methyl-5- alkylsalicyialdoxime and/or 3-methyl-5-alkyl-2-hydroxyacetophenone oxime, in reagent compositions for metal extraction/isolation. One such method is of extracting a metal from an aqueous ammoniacal solution. Metals that can be extracted include nickel, zinc and copper.
