FIELD: production of ferroalloys. SUBSTANCE: method involves discharging metal and slag from ore furnace into intermediate apparatus heated by electric power; holding till complete separation of metal reguli and drops from slag; discharging slag into slag pot through slag hole and into alloy casting ladle upon reception of second metal-and- slag charge into apparatus; repeating operations. Intermediate apparatus has vessel with oval-shaped shell having bottom made from sheet metal and lined with fire- resistant bricks. Vessel is used as bath. Shell and fire-resistant lining are provided with two holes: lower hole for discharging metal into ladle and upper hole for discharging waste slag into slag pocket. Apparatus has dome with three openings and fixed electrodes. Apparatus is mounted on immovable platform. EFFECT: increased efficiency and improved quality of separated metal. 3 cl, 2 dwg
