Extractante de cobre DY973N is used for the copper selective recovery in the hydrometallurgical processing of copper ores. It is a high-performance hydroxyoxime compound solvent extraction (SX) reagent for copper ions. Specifically used for SX-EW circuits that treating high-content copper ores and low-pH heap leaching solutions.
This image shows the results of our copper extraction experiment, providing a clear understanding of its extraction principle:
This is the actual copper extraction plant, you can see the extracted pure copper sulfate:
Following are the instructions of DY973N:
1. Chemical Composition & Blending Ratio of DY973N:
Active Ingredients: 5-nonyl salicylaldoxime (aldoxima) combined mixed with 2-hydroxy-5-nonyl acetophenone oxime (cetoxima).
Typical Active Ratio: Formulated in an optimized 7:3 volume ratio of aldoxime to ketoxime, includes 35% aldoxima, 15% cetoxima y 50% 260# aceite solvente. The high aldoxime percentage delivers severe copper-loading payloads, while the paired ketoxime functions as a mild kinetic modifier.

3. The Advantages of DY973N copper extractant:
Reduced Reagent Consumption: In practice, the consumption of single aldoxime will be 10 kg per metric ton cathode copper, but the consumption of DY973N will be under 5 kg per metric ton, will save the operating cost. So, you can top up the active organic phase with DY973N copper extractant in any ratio.
Superior Iron Rejection: With a selectivity threshold surpassing 2,300, will effectively lock out ferric iron.
4. Application scopes of DY973N copper extractant:
High-Grade Copper Leaching: Used for circuits encountering highly concentrated base metal PLS.
Low-pH Heap & Lixiviación: Ideal for mineral acid levels in the pregnant leach solution (por favor) fluctuate significantly or sit at low baselines.
Recycle Scrap Processing: To recycle copper from industrial etching effluents.
Por lo tanto, if you want to verify the miscible compatibility of DY973N with your current active organic phase, por favor contáctenos.
