Abstract

Способ извлечения скандия из красного шлама, включающий выщелачивание азотной кислотой и выделение его из раствора, отличающийся тем, что, с целью повышения выхода скандия при одновременном разделении с иттрием, выщелачивание проводят 25 - 30%-ной азотной кислотой при 90 - 100%-ном количестве от стехиометрически необходимого при 85 - 95C, а выделение скандия ведут экстракцией 7 - 10%-ным раствором триалкилфосфиноксида в керосине при соотношении объемов органической и водной фаз 1 : 2 - 3, кислотности 0,5 - 1,5 моль/л азотной кислоты.The method of extracting scandium from red mud, including leaching with nitric acid and separating it from solution, characterized in that, in order to increase the yield of scandium while simultaneously separating with yttrium, leaching is carried out with 25-30% nitric acid at 90-100% the amount of stoichiometrically required at 85 - 95C, and the release of scandium is carried out by extraction with 7-10% solution of trialkylphosphine oxide in kerosene with the ratio of the volumes of organic and aqueous phases 1: 2-3, acidity 0.5-1.5 mol / l nitric acid .
