FIELD: chemistry.
SUBSTANCE: invention relates to ferrous metallurgy and particularly to processing manganese material for smelting ferrosilicomanganese in arc furnaces containing less than 0.35% phosphorus. The charge contains the following, wt %: carbonaceous reducing agent 3-10, fluxing agent 7-20, ferrosilicon 1-7, and slag from production of manganese ferrous alloys being the balance.
EFFECT: invention increases the degree of extraction of manganese into metal, reduces specific consumption of electric powder and enables recycling of manganese-containing industrial wastes.
