FIELD: metallurgy.
SUBSTANCE: invention concerns pyrometallurgy. Particularly it concerns production of ferromanganese, and provides excluding of formation of dump waste slag at extraction of manganese from ore. In method it is implemented forming in furnace of reactionary capacity on the basis of fluorite melt, charging and reducing fusion of manganese ore, discharge from furnace of slag and ferromanganese. Before discharge from furnace of slag and ferromanganese into reactionary capacity it is add manganese ore in amount, depending on content of manganese in ore, content of manganese in slag and slag mass in furnace, till the receiving of slag with content 10-20% of manganese, used for preparation of welding flux.
EFFECT: excluding of manganese losses with dump waste slag and using of received slag for production of welding flux.
