FIELD: metal recovery processes. SUBSTANCE: invention relates to the recovery of manganese anions from aqueous solutions by ion- exchange materials that can be applied in ferrous and nonferrous metallurgies and also for treatment of trade and domestic effluents. Manganese anions are recovered by sorption at pH ≤ 7 and stirring on anionite (AM-2b) containing groups -CH2-N(CH3)2, -CH2-N(CH3)3.. EFFECT: enhanced process efficiency and reduced expenses.. 10 tbl, 7 ex
