  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.

  Provided are an extraction agent and extraction method that selectively extract and, at a low cost, recover gallium from an acidic solution containing gallium and zinc. The gallium extraction agent comprises an amide derivative represented by general formula (1). In the formula, R 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. The general formula preferably has a glycine unit, a histidine unit, a lysine unit, an aspartic acid unit, or an N-methylglycine unit. By extracting gallium from an acidic solution containing gallium and zinc by means of solvent extraction using the extraction agent, it is possible to selectively extract gallium.
