The present disclosure relates to a method of separating a mixture of oxalate salts of two or more of Ni (nickel), Co (cobalt) and Mn (manganese). Such methods may be used, for example, for the separation and recovery of two or more of Ni, Co, and Mn from waste lithium ion batteries or from production waste of lithium ion batteries or production waste of batteries or components of lithium ion batteries. 本公开涉及分离Ni(镍)、Co(钴)和Mn(锰)中的两种或更多种的草酸盐混合物的方法。这样的方法可用于例如从废旧锂离子电池组中或从锂离子电池组的生产废料或锂离子电池组的电池或组件的生产废料中分离回收Ni、Co和Mn中的两种或更多种。
