FIELD: production of high-quality manganese concentrate from low-grade manganese ores, concentrates and wastes. SUBSTANCE: proposed method includes precipitation of manganese from chlorine-containing solutions at addition of milk of lime and oxidation of manganese (II) by 45-70% from stoichiometry, washing and heat treatment of concentrate thus obtained. Proposed method ensures production of high-quality ecologically pure manganese concentrate at content of chlorine of up to 0.3% at complex used of resources. EFFECT: considerable reduction of toxic gaseous emissions at stages of metallurgical processing of concentrate. 3 cl, 5 tbl
