It is recommended to adopt a 2-extraction-1-backwash-1-wash process, using LIX984N as the extractant.
LIX984N is extracted in a sulfuric acid system, whereas this is an NH4Cl system. At the same time, LIX984N can only extract copper. Ni and Co are to be extracted using P204 or P507. This system is quite complex, and it is difficult to achieve the desired result in just one extraction step.
LIX984N is used to extract copper; the resulting solution is then precipitated to yield a residue, which is dissolved in sulfuric acid. NAF is used to remove calcium and magnesium, followed by the use of P204.507. For future discussions, contact 13550294746
If you want to recover Ni, Co, and Cu, the process will be more complex.
Procedure: Prepare a solution of metal ions at a certain concentration – add an extractant at a certain concentration – shake and allow phase separation; the pH value is the main factor to consider
Guys, what should we do if we can’t collect enough copper in 984n?
-- Under certain processing conditions, the extraction efficiency of LIX984N can reach over 98%. To achieve a higher extraction rate, it is necessary to adjust the pH accordingly; additionally, the feed solution should contain copper and other elements. --
Thank you. What is the structural formula of 984? Why can it be used for back-extraction with such a strong acid? Does it have good selectivity? For example, what is its ability to extract other metals at a pH of 2–2.5? Hehe, a beginner with many questions.
