Claims (4)

1. Способ извлечения скандия из кремнийсодержащих материалов, включающий измельчение и разложение материалов минеральными кислотами при нагревании и перемешивании с последующим разделением фаз и получением фильтрата, содержащего скандий, и твердого осадка, отличающийся тем, что измельчение проводят до получения частиц с размером 1-10 мкм, а последующее разложение проводят серной кислотой с концентрацией 150-500 г/л при 85-110oС.1. The method of extraction of scandium from silicon-containing materials, including grinding and decomposition of materials with mineral acids by heating and stirring, followed by phase separation and obtaining a filtrate containing scandium, and a solid precipitate, characterized in that the grinding is carried out to obtain particles with a size of 1-10 microns and the subsequent decomposition is carried out with sulfuric acid with a concentration of 150-500 g / l at 85-110 o C. 2. Способ по п.1, отличающийся тем, что измельченный исходный материал переносят в предварительно нагретый раствор серной кислоты. 2. The method according to claim 1, characterized in that the crushed starting material is transferred to a pre-heated solution of sulfuric acid. 3. Способ по п.1, отличающийся тем, что разложение проводят при соотношении твердой фазы к жидкой от 1 : 4 до 1 : 7 в течение 1-6 ч. 3. The method according to claim 1, characterized in that the decomposition is carried out at a ratio of solid to liquid from 1: 4 to 1: 7 for 1-6 hours 4. Способ по п.1, отличающийся тем, что осадок после фильтрации промывают водой или разбавленным раствором НСl при соотношении твердой фазы к жидкой от 1 : 3 до 1 : 5 и температуре 20-50oС.4. The method according to claim 1, characterized in that the filter cake is washed with water or a dilute HCl solution at a ratio of solid to liquid from 1: 3 to 1: 5 and a temperature of 20-50 o C.
