PROCESS FOR THE ELIMINATION OF COPPER VALUES FROM AN ACIDIC AQUEOUS SOLUTION BY MENS OF A LIQUID-LIQUID EXTRACTION

摘要

A process for the separation by liquid-liquid extraction of valuable amounts of copper from an acidic aqueous solution containing valuable amounts of copper. The process comprises contacting the aqueous acidic solution with an organic extraction medium comprising (a) an organic solvent substantially immiscible with water (b) a hydroxy-oxine or a mixture of hydroxy-oximes capable of extracting valuable amounts of copper and (c) an alphabeta-dioxime or a mixture of alphabeta-dioxides.
