FIELD: metallurgy.SUBSTANCE: proposed device comprises the frame with slag compression head, mould for collection of compressed metal with slag output device, pipe to feed vacuum to the latter via through opening made in mould side wall, and seal arranged in clearance between slag output device and mould. Note here that slag compression head has ribbed outer surface while slag output device bottom has one or several through drain holes and/or open pores. A seal may be arranged between compression head and slag output device. Said slag output device inner surface facing the slag can have one or several ribs. Hollow head may be furnished with two or more air-cooled pipes. Slag output device and/or head may be equipped with vibrator. This device may incorporate one or several magneto hydrodynamic pumps to force metal to said one or several drain holes and/or open pores.EFFECT: higher yield of nonferrous metal from slag.6 cl, 3 dwg |
