FIELD: ferrous metallurgy; ferromelting process; melting carbon ferromanganesian process. SUBSTANCE: used as manganese- containing raw material is mixture of chemical concentrate and iron- manganese concretions at the following ratio of components, mass-%: chemical concentrate, 70-90 and iron-manganese concretion, 10-30. Proposed charge extends field of application of starting iron-manganese concretions and concentrates, increases extraction of manganese and enhances ratio of slag. EFFECT: enhanced efficiency; reduced power requirements. 3 cl, 2 tbl, 1 ex
