DY984N extractant
2-hydroxy-5-nonylsalicylaldehyde oxime and 2-hydroxy-5-nonyl ketoxime blend
CAS 50849-47-3 / 59344-62-6
DY984N is an aldoxime–ketoxime blend for copper solvent extraction: 25% aldoxime, 25% ketoxime and 50% solvent oil, with a concentrate grade DY984N-C at 35/35/30. The blend loads and strips in the same circuit, avoids third-phase formation and reaches a copper net transfer of 3.4 g/L with a Cu/Fe selectivity of 2279 or better.
- 3.4 g/L net transfer
- ≥92% extraction in 30 s
- Cu/Fe selectivity ≥2279
- No third phase

Typical use
Copper SX–EW circuits treating heap, dump or concentrate leach solutions, including plants that need a drop-in reagent comparable with an existing organic.
- 01Specify the circuit from the copper tenor, acidity and chloride level of the pregnant leach solution.
- 02The concentrate grade is used where higher copper transfer per unit organic volume is required.
- 03Plant consumption is around 2 kg of reagent per tonne of copper cathode in operating references.
