DY88 Ketoxime extractant

DY88 Ketoxime extractant is used for special condition of copper and other rare earths extraction, just like that if you want to use ammonia to obtain Cu2O, you have to use the DY88 Ketoxime extractant, aldehyde oxime can not be used in alkaline reaction condition.

DY88 Ketoxime Extractant is a highly specialized hydroxyoxime-based solvent extraction (SX) reagent engineered specifically for challenging, non-standard hydrometallurgical operations. Aldoxime extractants can’t be used in high-pH and ammoniacal environments, but DY88’s pure 2-Hydroxy-5-nonyl ketoxime molecular architecture delivers exceptional chemical stability in this condition.

Ammoniacal Copper Leaching & Production:

When processing complex copper scrap, chalcopyrite concentrates, or specific oxidized ores using ammonia/ammonium salt leaching, the target is often to generate premium cuprous oxide.

The DY88 Advantage: DY88 acts as the critical extraction bridge. It selectively extracts directly from highly alkaline, ammoniacal solutions without loading the ammonia matrix. This ensures an ultra-pure advanced solution feed necessary to precipitate high-grade cleanly, ensuring no organic poisoning or physical emulsification occurs in alkaline mediums.
