In hydrometallurgy, Copper solvent extraction reagent is the core driver of chemical separation, enabling the selective transfer of copper ions from a low-grade Pregnant Leach Solution (LÜTFEN) to a highly concentrated electrolyte for electrowinning (EW).

Why Blended Copper Solvent Extraction Reagent Dominate Modern Operations?

Pure aldoximes require kinetic modifiers to strip properly, but these modifiers can accelerate chemical degradation and increase phase separation times. Pure ketoximes struggle to achieve high recovery rates if the feed PLS drops below pH 1.5.

To bypass these limitations, modern formulations utilize non-modified aldoxime/ketoxime blends. By mixing a strong aldoxime with a highly stable, easily stripped ketoxime, the net copper transfer, robust stability, and rapid phase separation can achieve outstanding without the baggage of synthetic modifiers.
