摘要： To efficiently and selectively recover scandium from an acid solution containing calcium, magnesium and scandium. In the present invention, an acid solution containing calcium, magnesium and scandium is brought into contact with a scandium recovering resin impregnated with an amide derivative represented by the following general formula for an hour or more. In the formula, R1 and R2 each represent the same or different alkyl groups. The alkyl group can be a straight chain or a branched chain. R3 represents a hydrogen atom or an alkyl group. R4 represents a hydrogen atom or any group other than an amino group, which is bound to the α carbon as an amino acid. The amide derivative is preferably any one or more of glycinamide derivatives, histidinamide derivatives, lysinamide derivatives and aspartic acid amide derivatives.
