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.

In practice, to produce one metric ton cathode copper, the consumption of Aldoxime will more than 10kg, but Compound Aldoxime & Ketoxime (DY988N) will less than 5kg. The consumption of Compound Aldoxime and Ketoxime reagent will less than single Aldoxime 3-6kg.

Our engineer is operating a copper extraction plant, the consumption of DZ988N is 2 kg to per ton copper cathode. The purity of copper cathode can reach 99.9982%. The data as below:

Laboratory test process:

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 DY988N, 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 H2SO4 to 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.

If the calculated concentration more than 20%, please change the phase ratio of organic phase to aqueous phase=2:1.

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.
