Most customer worry to break their working system at beginning of use our extraction reagent, this is normal concern for any person. If you can pass through the below test, you can free to use it without concern:Use our reagent and your using reagent to do a laboratory test one by one, so as to compare the extraction ability, phase separation time and situation;Take your using organic phase, mix with our organic (V/V, 1:1), then do a laboratory test to check the extraction ability, phase separation situation, and confirm whether it has untoward effect.If above tests all be regular, it means that both reagents can be mixed to use together.Laboratory test process: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, 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);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: https://www.youtube.com/watch?v=-mQ8iWH1LUo In practice, if the calculated concentration more than 20%, please change the phase ratio of organic phase to aqueous phase=2:1.

On June 23th, 2020, our company's President Wang, Professor Guo, Manager Guo, Zhou Zhenyu went to Jinchuan Company's nickel salt plant for annual technical services and on-site communication.A total of 12 peoples, including General Manager Gong, Director Meng, Deputy General Manager Wang Qiang, Director Dong, Secretary Ming of the Nickel Salt Plant of Jinchuan Company, and the team leaders and technicians of Jinchuan Company participated attended the on-site communication meeting.First of all, Mr. Gong of Jinchuan Group expressed a warm welcome to our company’s arrival, mentioning the correct diagnosis and solutions that our company solved the problems in their production last year, helped them to resume normal production, and made the battery-grade nickel sulfate production capacity overed 100,000 tons, he hope our company can increase the frequency of on-site communication and service to them.Mr. Wang of our company expressed gratitude to Jinchuan Company for providing us the on-site learning and communication chance, and promised that if Jinchuan Company needs our support, we will certainly arrive there as fast as possible.Professor Guo took out the test report and diagnosis result of Phospogram that they mailed sample to us, got their high recognition and approbation.After Professor Guo introduced the research and development results and application of our new extractant, Mr. Gong was very interested. He suggested to establish a joint research group on the spot and instructed Mr. Dong to be responsible for the project and start work as soon as possible.Director Dong was very interested in our C301 extractant that introduced by Professor Guo, and asked to provide samples for experimentation, and was willing to do the pilot test in Jinchuan Group.After Professor Guo explained the influence of solvent oil in the wasted water and product quality in normal production, he was resonated with customers again. Deputy General Manager Wang Qiang introduced that they were bothered by poor solvent oil many years and eliminated two kinds of solvent oil supplier, but still did not solve the problem fundamentally. Mr. Gong asked us to provide workable solvent oil samples for DZ272 to help them get out of this predicament as soon as possible.Factory Manager Meng said that there is a kind of suspended solids in their producing process, and hope we can help them to give them a solution; Professor Guo requested them to provide the sample, we will find out the cause and give them solution in the shortest time.Through this visiting to Jinchuan Company, we not only help customer to solve the problems encountered in the current use of extractant, but also deepened the cooperative relationship with customers, strengthened the confidence of our products and technology, and made our cooperation more stable, long-term and extensive. Let us have more confidence in our future work to provide better services to customers with high quality and high efficiency, so that customers can use our products more confidently.

As an important part of producing an exquisite wholesale solvent , high-quality raw materials selection is essential for the producer. Besides that, the raw materials also have a great influence on its price, which is one of the important factor taken into buyer's consideration. The quality of raw materials should be attached great importance as well as its great durability. Before being processed, raw materials should be tested strictly.
