Extraction of copper
1. Used for copper ore.
2. Same as Lix984, lix973, N902.
3. Better than Lix984, lix973
Industrial copper extractant
The chemical equation as below:
KEY POINT: High extraction capacity, Easy phase separation, Easy reverse extraction, Good chemical stability, High inoxidability. MAIN ADVANTAGE:
1. Ketoxime: Extraction capacity is slight smaller, but the property of phase separation is excellent, easy reverse extraction, chemical stability is good, and strong inoxidability. 2. Aldoxime: Extraction capacity is slight higher, but can be used for greater acidity liquid. However the reverse extraction, phase separation and stability are less than Ketoxime. 3. The mixed Ketoxime and Aldoxime own the both advantages.
In a word, it is mixed Ketoxime and Aldoxime, not only has good extraction capacity, but also has good phase separation, and easy reverse extraction, good chemical stability and strong inoxidability.
1. Classification of copper extraction solvent. Compound copper extraction solvent of Ketoxime and Aldoxime can be used alone or mixed with LIX984, LIX973, M5640 and N902 in any ratio. DZ88: The mixture of Ketoxime and high flash point kerosene. DZ988: The mixture of equal volume Ketoxime and Aldoxime mixed with high flash point kerosene. DZ973: The mixture of Aldoxime and Ketoxime in volume of 7:3 mixed with high flash point kerosene. DZ902: Aldoxime add specific anti-oxidant and mixed with high flash point kerosene.
Feature of Ketoxime: Extraction capacity is slight smaller, but the property of phase separation is excellent, easy reverse extraction, chemical stability is good, and high inoxidability. Features of Aldoxime: Extraction capacity is slight higher, but can be used for greater acidity liquid. However the reverse extraction, phase separation and stability are less than Ketoxime. The best copper extraction solvent is the mixture of Ketoxime and Aldoxime, owning both of the advantages.
2, Stability of copper extraction solvent DZ series copper extraction solvents are the mixtures of Ketoxime and Aldoxime, don’t add any modifier. But the copper extraction solvent which named M5640, N902, CP-150, AD-100 and so on are all single extraction solvent of Aldoxime (In fact all are N902). In order to improve the performance of reverse extraction, manufactory has added various modifier during the producing process, that will reduce the stability of oxime, easy to degrade copper extraction solvent, especially in the condition of Cl- and No3-, the degradation shall be very quickly.
3, Viscosity of extraction solvent Extraction solvent’s viscosity will effect two-phase separation, if the viscosity is high, two-phase separation will be slow, that will carry more organic phase. But the compound extraction solvent of Ketoxime and Aldoxime will avoid the defect obviously, if the liquid contain a lot of copper, we can increase the concentration of extraction solvent, so that we can improve the extraction efficiency.
4, This is our patented production.

Q: How do I know the copper is much pure if we use DZ988?
A: You wouldn’t find black spot on the copper if you use DZ988 solvent. But these black spot is appearing on the copper when you use other copper solvent.
Q: What’s the difference of boiling point compared with other copper solvent?
A: The boiling point of DZ988 is 300°C but others always around 62°
Q: Can we find the difference by test?
A: Yes and you’ll find DZ988’s great advantage after more than 300 times test.
Q: If we buying kerosene mixed solvent means a big and more expensive for us, can you provide us pure DZ988?
A: Yes we can provide you pure DZ988 solvent without kerosene. After you getting our solvent you have to get it heating to 70°C - 80°C when mix the kerosene in.
