The selective separation of manganese and cobalt from the leaching solution of spent ternary lithium batteries by nickel saponification extraction was studied. The effects of extraction agent concentration, pH, phase ratio, saponification rate, and acid concentration on the extraction and stripping performance were systematically investigated. The results show that after adjusting the pH to 4.8 with Ni(OH)2 and significantly reducing the contents of Fe, Al, and Cu, nickel saponification P204 can achieve efficient extraction of manganese under two-stage cross-flow conditions, with an extraction rate exceeding 99%. Meanwhile, the co-extraction rates of cobalt and lithium are controlled at 18.67% and 9.89%, respectively. After low-acidity washing and sulfuric acid stripping, the stripping rate of manganese reaches 99.96%. Further, nickel saponification P507 is used for two-stage cross-flow extraction of cobalt, achieving a cobalt extraction rate of 99.92% and a co-extraction rate of lithium of 13.68%. After washing and stripping, the stripping rate of cobalt can reach 99.87%. The process significantly reduces the introduction of Na+ impurities while achieving efficient separation of manganese and cobalt, leaving nickel and lithium in the system. It provides experimental technical references for the high-purity recovery of multi-metal resources and has potential for further industrial application.

研究了采用镍皂化萃取法对废旧三元锂电池浸出液中锰、钴进行选择性分离,系统考察了萃取剂浓度、pH、相比、皂化率、酸浓度等因素对萃取与反萃取性能的影响。结果表明:在用Ni(OH)2调节pH至4.8,并明显降低Fe、Al、Cu含量后,采用镍皂化P204在二级错流条件下可实现锰的高效萃取,萃取率大于99%,同时可将钴、锂的共萃取率分别控制在18.67%和9.89%;经低酸度洗涤与硫酸反萃取处理后,锰反萃取率达99.96%;进一步采用镍皂化P507二级错流萃取钴,钴萃取率达99.92%,锂共萃取率为13.68%;经洗涤与反萃取,钴反萃取率可达99.87%。该工艺可在显著降低Na+杂质引入的同时,实现锰、钴的高效分离,并将镍和锂留在体系中,能为多金属资源的高纯度回收提供技术参考,具有进一步工业化应用潜力。

研究了采用镍皂化萃取法对废旧三元锂电池浸出液中锰、钴进行选择性分离,系统考察了萃取剂浓度、pH、相比、皂化率、酸浓度等因素对萃取与反萃取性能的影响。结果表明:在用Ni(OH)2调节pH至4.8,并明显降低Fe、Al、Cu含量后,采用镍皂化P204在二级错流条件下可实现锰的高效萃取,萃取率大于99%,同时可将钴、锂的共萃取率分别控制在18.67%和9.89%;经低酸度洗涤与硫酸反萃取处理后,锰反萃取率达99.96%;进一步采用镍皂化P507二级错流萃取钴,钴萃取率达99.92%,锂共萃取率为13.68%;经洗涤与反萃取,钴反萃取率可达99.87%。该工艺可在显著降低Na+杂质引入的同时,实现锰、钴的高效分离,并将镍和锂留在体系中,能为多金属资源的高纯度回收提供技术参考,具有进一步工业化应用潜力。

The selective separation of manganese and cobalt from the leaching solution of spent ternary lithium batteries by nickel saponification extraction was studied. The effects of extraction agent concentration, pH, phase ratio, saponification rate, and acid concentration on the extraction and stripping performance were systematically investigated. The results show that after adjusting the pH to 4.8 with Ni(OH)2 and significantly reducing the contents of Fe, Al, and Cu, nickel saponification P204 can achieve efficient extraction of manganese under two-stage cross-flow conditions, with an extraction rate exceeding 99%. Meanwhile, the co-extraction rates of cobalt and lithium are controlled at 18.67% and 9.89%, respectively. After low-acidity washing and sulfuric acid stripping, the stripping rate of manganese reaches 99.96%. Further, nickel saponification P507 is used for two-stage cross-flow extraction of cobalt, achieving a cobalt extraction rate of 99.92% and a co-extraction rate of lithium of 13.68%. After washing and stripping, the stripping rate of cobalt can reach 99.87%. The process significantly reduces the introduction of Na+ impurities while achieving efficient separation of manganese and cobalt, leaving nickel and lithium in the system. It provides experimental technical references for the high-purity recovery of multi-metal resources and has potential for further industrial application.
