DY973N Copper solvent extraction reagent

DY973N Copper Solvent Extraction Reagent is a high-performance, formulated hydroxyoxime extractant. It is engineered for the selective recovery and concentration of copper ions from acidic Pregnant Leach Solutions (PLS) via the Solvent Extraction-Electrowinning (SX-EW) metallurgical process.

Refer below picture, you can understand the working principle of our copper extractant:

DY973N belongs to the compounded (blended) oxime class of reagents, utilizing a precise mixture of both an aldoxime and a ketoxime to balance extraction kinetics with stripping efficiency. It serves as a commercially efficient, direct drop-in alternative to industry-standard formulations.

DY973N Copper solvent extraction reagent can be used alone or mixed with LIX984N, LIX973N, M5640, M5774, CP-150 and N902 in any ratio.

You can free to add our reagent to your extraction system in any ratio.

In practice, to produce one metric ton cathode copper, the consumption of Aldoxime will more than 10kg, but Compound Aldoxime & Ketoxime will be less than 5kg. The consumption of Compound Aldoxime and Ketoxime reagent will less than single Aldoxime 3-6kg.

How to make sure our reagent is workable in your plant:
Do above laboratory separately to compare the extraction ability, phase separation time and situation with your using reagent; Take your using organic phase, mix with our organic (V/V, 1:1), then do above laboratory test to check the extraction ability, phase separation situation, and confirm whether it has untoward effect.

If above tests all be normal, it means that both reagents can be mixed to use together.

Please check our engineer designed copper extraction plant. This is most economical small plant, the producing capacity is 3 tons copper cathode daily. We can do the turnkey project.
