本方法是用叔基一元羧酸作为萃取剂,钴就可以从含有镍钴的浓氨溶液中提取出来。在萃取过程中,有机相优先将钴萃取,镍留在净化溶液中,在有机相中回收钴,将钴变成盐,或变成氧化物或金属粉末。镍可用任何合适的技术从净化溶液中回收,如萃取法、硫化沉淀。然后回收铵盐。 This method is the use of tertiary monocarboxylic acid as an extractant, cobalt can be extracted from concentrated ammonia solution containing nickel and cobalt out. During the extraction, the organic phase preferentially extracts the cobalt, leaving the nickel in the cleaning solution, recovering the cobalt in the organic phase, turning the cobalt into salt, or turning it into an oxide or metal powder. Nickel can be recovered from the decontamination solution by any suitable technique, such as extraction, and sulphidation precipitation. The ammonium salt is then recovered.
