Title:
METHODS OF METAL EXTRACTION USING OXIMES
Document Type and Number:
WIPO Patent Application WO/2012/116305
Kind Code:
A3
Abstract:
Provided are methods using ketoximes and/or aldoximes, including 3-methyl-5- alkylsalicylaldoxime 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 a nitrate-containing aqueous solution. Another such method is of extracting a metal from an aqueous ammoniacal solution. A third method is of multi-metal extraction based on a predetermined pH.
