Solvent extraction. Extractants. At low pH ( ) the orthohydroxyoxime extractant complexes the Cu. During backextraction (stripping stage) the pH is lowered further, releasing the Cu, and regenerating the hydroxyoxime for recycle to the extraction stage. Aqueous feeds (leach solution) typically contain more iron per litre than copper.
