1. Способ получения концентрата скандия из скандийсодержащего раствора, включающий сорбцию скандия на ионите, промывку насыщенного ионита, десорбцию скандия из насыщенного ионита раствором карбоната натрия с получением десорбированного ионита, который направляют на повторную сорбцию скандия, и раствора десорбции, который предварительно подкисляют с последующим осаждением концентрата скандия путем его обработки гидроксидом натрия или аммиаком, отличающийся тем, что сорбцию проводят на ионите с фосфор- и сульфосодержащими функциональными группами, промывку ионита проводят раствором, содержащим 20-200 г/дм3 серной кислоты H2SO4 и 1-20 г/дм3 перекиси водорода.1. A method of obtaining a scandium concentrate from a scandium-containing solution, including sorption of scandium on an ion exchanger, washing of a saturated ion exchanger, desorption of scandium from a saturated ion exchanger with a sodium carbonate solution to obtain a desorbed ion exchanger, which is sent to re-sorption of scandium, and a desorption solution that is pre-acidified followed by precipitation scandium concentrate by treatment with sodium hydroxide or ammonia, characterized in that the sorption is carried out on an ion exchanger with phosphorus and sulfonic functional groups, washing the ion exchange resin is carried out with a solution containing 20-200 g / dm 3 of sulfuric acid H 2 SO 4 and 1-20 g / dm 3 of hydrogen peroxide. 2. Способ по п. 1, отличающийся тем, что перед осаждением концентрата скандия подкисленный раствор десорбции пропускают через слой высокоосновного анионита.2. The method according to p. 1, characterized in that before the precipitation of the scandium concentrate, an acidified desorption solution is passed through a layer of highly basic anion exchange resin.
