FIELD: extraction of scandium from scandium-containing ores and minerals, particular, in process of dissolution of hydrate sediments, separated from hydrolysis acid, product of ilmenite processing into pigment titanium dioxide. SUBSTANCE: hydrate sediments are dissolved in nitric acid at concentration of excessive nitric acid of 80-100 g/l, at initial S:L=(1:8)-(1: 12), and formed suspension is neutralized by ammonia at pH 0.8-1.0, and scandium is extracted from solution. EFFECT: higher efficiency. 2 tbl
