DZ973N specially chemical reagent for extracting copper from copper leaching solution used in copper mining

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.

Supply 200ml free sample for test.

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.

DETAILED DESCRIPTION:

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.

Patent No.: 2010100300261.7

During the practice, the reaction (Extraction & Reextraction) must be happened over 300 times, the advantage will be shown clearly.
