Abstract

1. Способ извлечения скандия экстракцией из хлоридных растворов с использованием трибутилфосфата в качестве компонента органической фазы, отличающийся тем, что процесс проводят смесями трибутилфосфата с элементным йодом, взятом в количестве 12,5-76 г/л, а реэкстрагируют металл водой.2. Способ по п. 1, отличающийся тем, что при экстракции скандия из железосодержащих растворов катионы железа(3+) предварительно восстанавливают до железа(2+).1. The method of extraction of scandium by extraction from chloride solutions using tributyl phosphate as a component of the organic phase, characterized in that the process is carried out with mixtures of tributyl phosphate with elemental iodine taken in an amount of 12.5-76 g / l, and the metal is re-extracted with water. 2. The method according to claim 1, characterized in that during the extraction of scandium from iron-containing solutions, iron cations (3+) are preliminarily reduced to iron (2+).
