DY984N Copper leaching solvent is a un-modified aldoxime-ketoxime reagent. It only can extract copper ions (Cu²⁺) from a pregnant leach solution (PLS) then release (strip) into a highly concentrated sulfuric acid solution, to generate a rich electrolyte suitable for electro-winning (EW).

The Core Advantages of DY984N copper leaching solvent:
Drop-In Compatibility: DY984N features universal miscibility. It can be added directly to your extraction system without causing phase separation abnormalities, or precipitate clotting.
Radically Reduced Organic Entrainment: It can promote rapid phase disengagement in the settler. Limits both organic and aqueous exchange entrainment, to save the loss of solvent.
Premium Cathode Protection: With a selectivity ratio exceeding 2,500, DY984N prevents ferric iron to contaminat your electrowinning circuit. This maintains maximum current efficiency and get good quality copper cathodes.
Typical Application of DY984N Copper leaching solvent in an extraction cycle:
1. Extraction: Mix the diluted DY984N solvent with the copper-rich PLS (aqueous phase) in a mixer-settler. The extractants selectively bind to copper ions, transferring them into the organic phase.
2. Separation: Settle the mixtur, forming two immiscible phases: the copper-loaded organic phase and the copper-depleted aqueous raffinate.
3. Stripping: The copper-loaded organic phase will be mixed with a strong sulfuric acid solution. The high acidity causes the extractants to release the copper ions into the aqueous phase, creating a rich electrolyte that is high copper content.
4. Electrowinning: The rich electrolyte will be sent to the electrowinning tankhouse, where an electrical current is applied, plating out pure copper (more than 99.995%) onto cathodes.
