Compare with other Copper extraction reagents:

Compound copper extraction reagent of Ketoxime and Aldoxime 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 using reagent in any ratio.

In practice, to produce one metric tonne cathode copper, the consumption of Aldoxime will more than 10kg, but Compound Aldoxime & Ketoxime (DZ988N) will less than 5kg. The consumption of Compound Aldoxime and Ketoxime reagent will less than single Aldoxime 3-6kg.

 

  Laboratory test procedure:

Dilute copper extraction reagent: Base the Cu⁺content of PLS (Lixivium liquid), add suitable No.260 solvent oil to dilute the organic. Such as the content of copper is 5 g/L, if we use DZ988N, the copper net transfer is 2.7 g/L, 0.27 g/100ml, 5/0.27=18.5, so the organic should be dilute to 19%. (Laboratory test usually use 100 ml);

 

Pour the prepared organic phase to PLS: according to the volume rate of 1:1, and fully mix it over 3 minutes, then record the time to stand the phase till it is separated, you will know the phase separation time. Then pour out the inorganic solution;

 

Pour 180g/L H2SO4to the left organic phase in rate of 2:1-4:1 (V:V), and mix it 3 minutes, then record the back extraction time, we will get pure CuSO4. The reverse extracted organic phase can be used again.

  

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 of our reagent and your using reagent, (50-100ml);

 

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 no problem, it is certificated that the reagents can be mixed together for using.
