ABSTRACT:
An improvement in the process of extracting metal from aqueous acidic solution using a quaternary ammonium thiocyanate extractant wherein a special amount of thiocyanate ion is introduced into the aqueous solution prior to or contemporaneously with the extraction. Results achieved are better extractions with little or no additional loss of thiocyanate ion in the aqueous raffinate.
