  The objective of the present invention is to selectively extract cobalt from an acidic solution containing a high concentration of manganese. This cobalt extraction method extracts cobalt from an acidic solution containing manganese and cobalt by subjecting the acidic solution to solvent extraction by means of a valuable metal extraction agent comprising an amide derivative represented by general formula (I). The valuable metal extraction agent is represented by the general formula. In the formula: R1 and R2 each represent the same or different alkyl group; R3 represents a hydrogen atom or an alkyl group; and R4 represents a hydrogen atom or any given group aside from an amino group bonded to the a carbon as an amino acid. Preferably, the general formula has a glycine unit, a histidine unit, a lysine unit, an aspartic acid unit, or an N-methylglycine unit. Preferably, the pH of the acidic solution is 3.5-5.5 inclusive.

  本发明的目的是从含有高浓度锰的酸性溶液中选择性地提取钴。本发明的钴萃取方法是从含有锰和钴的酸性溶液中萃取钴，其方法是将酸性溶液用溶剂萃取，溶剂萃取剂包括通式(I)表示的酰胺衍生物。有价金属萃取剂由通式表示。式中R1 和 R2 分别代表相同或不同的烷基；R3 代表氢原子或烷基；R4 代表氢原子或除作为氨基酸键合在碳上的氨基外的任何基团。通式中最好有一个甘氨酸单元、一个组氨酸单元、一个赖氨酸单元、一个天冬氨酸单元或一个 N-甲基甘氨酸单元。酸性溶液的 pH 值最好在 3.5-5.5 之间。

  The objective of the present invention is to selectively extract light rare earth metals, and by extension, europium, from an acidic solution containing a plurality of types of rare earth metal. This valuable metal extraction agent is represented by the general formula. In the formula: R 1 and R 2 each indicate the same or different alkyl group; R 3 indicates a hydrogen atom or an alkyl group; and R 4 indicates a hydrogen atom or any given group other than an amino group bonded to the α carbon as an amino acid. Preferably, the general formula has a glycine unit, a histidine unit, a lysine unit, an aspartic acid unit, or an N-methylglycine unit. Preferably, when extracting europium using the extraction agent, the pH is adjusted into the range of 2.0-3.0 inclusive, and when selectively extracting light rare earth metals, the pH is adjusted to 1.7-2.7 inclusive.

  Provided is a method that selectively extracts and, at a low cost, recovers indium from an acidic solution containing indium and gallium. The present invention is a method that is for isolating a valuable metal and that, by means of subjecting an acidic solution containing indium and gallium to a solvent extraction that is by means of an extraction agent comprising an amide derivative represented by a general formula, extracts indium from the acidic solution. In the formula, R 1 and R 2 each indicate the same or a different alkyl group, R 3 indicates a hydrogen atom or an alkyl group, and R 4 indicates a hydrogen atom or any given group, other than an amino group, bonded to the α-carbon as an amino acid. The general formula preferably has a glycine unit, a histidine unit, a lysine unit, an aspartic acid unit, or an N-methylglycine unit.
