摘要：FIELD: chemistry. ^ SUBSTANCE: invention can be used in hydrometallurgy during sorption extraction of rare elements from solutions formed during ore leaching. To realise the method, the anionite is treated with acidic solutions of fluorides containing 2.5 g-eq/l F- and 10% sulphuric and nitric acid in static conditions with contact time of 2-3 hours. The acid solution used is acidic mother solutions from the extraction process stage of hydrometallurgical extraction of rare metals from crude ore, containing 10% H2SO4 and 0.06-0.15 g-eq/l of the nitrate ion NO3. ^ EFFECT: invention reduces the cost of the method for desiliconisation of anionites while maintaining mechanical strength of the anionite and residual content of SiO2. ^ 2 ex, 1 tbl
