The possibility of scandium separated from impurities by saturated TWEX phase washing by mixed solution Н2О2 (3%) + С2Н2О4 (100-110 g∙L-1) at different solid –liquid phase ratio was investigated. Maximum effective scandium separation from such impurities as Al, Fe, Zr, Th was reached by the use of solution Н2О2 (3%) + С2Н2О4 (110 g∙L-1) at solid – liquid phase ratio 1:25. It is necessary to choose another stripping solution for effective Ti and U elution
