1 Metal Leaching Reagents We professionally focus on research and development metal leaching reagent! Our Copper extraction reagents have good performance on copper leaching, our engineer had built over twenty copper leaching plant in China, Zambia and Congo-Brazzaville etc. We have rich advanced experience on copper SX-EW technology. If you use our products, we will in charge of the all service for pilot test and producing process suggestion, especially to solve the problems of third phase. Our new product DZ-272 has best ability on high content of Co-Ni separation, the ability over 20 times than normal old reagent (P507), also the price is very low. And we have other leaching solvent for rare earth and some rare elements, please learn about the details of our products patiently. 1. DZ series Copper leaching reagents:

3 Content and characteristics: TYPE DZ902 DZ88 DZ988N DZ973N Component Aldoxime Ketoxime Advantage High extracting ability, it is workable for high copper ion and high acidity condition The ability of phase disengagement is excellent, easy to reverse extraction, chemical stability is good, and has strong inoxidability. Aldoxime+Ketoxime (V:V=1:1) Not only has good extracting ability, but also has good phase disengagement ability, easy to reverse extraction, has good chemical stability and strong inoxidability. Aldoxime+Ketoxime (V:V=7:3) Not only has good extracting ability, but also has good phase disengagement ability, easy to reverse extraction, has good chemical stability and strong inoxidability. Defect 1. Must add a lot of Modifier and Antioxidant, easy to produce 3rd phase, the consumption will be increased. 2. The ability of reverse extraction, phase disengagement and stability are less than Ketoxime. The extracting ability has a little slightly Non Non Result Not recommend Special usage Recommend Recommend Component compare of major Copper leaching solvent:

4 Classification of copper extraction reagent: Compound copper extraction reagent of Ketoxime and Aldoxime can be used alone or mixed with LIX984N, LIX973N, M5640, M5774, CL-150 and N902 in any ratio. You can free to add our reagent to your using reagent. In practice, to produce 1 ton cathode copper, the consumption of Aldoxime will more than 10kg, but mixed Aldoxime & Ketoxime (like DZ988N) will less than 5kg. The consumption of mixed Aldoxime and Ketoxime reagent will less than single Aldoxime 3-6kg. 2. Laboratory test procedure: a. 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, 5/0.39=12.8, so the organic should be dilute to 13% (V:V) (5.2 g/l*0.75=3.9 g/l=0.39 g/100ml. Laboratory test usually use 100ml, but 50ml is enough); b. 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; c. 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. Please click here to view the operation video: 3.

Description (Patent No ) DZ-272 s separation coefficient is more than 20 times of P507 on same condition, it is applied to high content Ni-Co solution, also does not has extraction ability for calcium (Ca), can re-extract iron on the condition of low content sulfuric acid. DZ-272 can be dissolved each other with fat diluent and aromatic diluent fully, and the stability is good, water-soluble ability is low. DZ-272 can extract Ni-Co in the system of sulfuric acid and chloride, also can extract rare earth elements of gallium (Ga), molybdenum (Mo), germanium (Ge), thulium (Tm), ytterbium (Yb), lutetium (Lu) etc. Advantage: DZ-272 s effective component can over 90%, has good extraction ability, high selectivity, low water-soluble ability, easy to be re-extracted. DZ-272 s extraction series is little, can save a lot of investment on equipment and people, will save much more cost of products. DZ-272 s price is lower than other competitor s products very much.
