FIELD: ferrous metallurgy; production of low- phosphoric manganese alloys obtained from lean ores, namely, ferromanganese and silicomanganese. SUBSTANCE: method includes production of low-phosphoric manganese alloys from lean manganese ores in three converter-type units located in succession. Consumption of metallic additive gm.ad is calculated for each unit according to definite mathematical dependence. EFFECT: high degree of extraction of manganese; increased productivity. 1 ex
