摘要：
从至少含有镍和钴的酸性树脂洗出液中回收镍和钴的方法，所述方法包括以下步骤：(a)使用不相混的有机试剂(18)处理所述洗出液以便选择性地吸收所述洗出液中的大部分的钴以及一部分任意存在的铜、锌和锰，剩下含有所述镍和少量杂质的萃余液；(b)中和所述萃余液以便将所述镍沉淀为氢氧化镍(19)；(c)从该有机试剂(22)中反萃取所述钴；以及(d)回收该钴(23)。
摘要（英）：

A process for the recovery of nickel and cobalt from an acidic resin eluate containing at least nickel and cobalt, said process including the steps of : (a) treating the eluate with an immiscible organic reagent (18) to selectively absorb the majority of the cobalt, and a portion of any copper, zinc and manganese present in the eluate, leaving a raffinate containing the nickel and minor impurities; (b) neutralising the raffinate to precipitate the nickel as nickel hydroxide (19); (c) stripping the cobalt from the organic reagent (22); and (d) recovering the cobalt (23).
