PROCESS FOR EXTRACTION OF METAL VALUES FROM AQUEOUS SOLUTIONS OF METAL SALTS CONTAINING HALET OR PSEUDO-HALET AND COMPOUND ANIONS

摘要

Metal values are extracted from aqueous solutions containing halide or pseudohalide anion using 1,1'-substituted 2,2'-biimidazole or bibenzimidazole compounds. Useful for the solvent extraction of zinc and copper from chloride leach solutions.
