摘要

FIELD: mining. ^ SUBSTANCE: device comprises cylindrical chamber whose side is an electrode, central electrode that is made of two cylinders provided with vertical slots and arranged in a staggered order. The top section of the inner cylinder of the central electrode has an opening for discharging the particles of barren rock. The device has additional electrodes made of rings and mounted on the top and bottom sides of the closed cylindrical chamber and additional electrodes mounted on the outer side of the bottom of the closed cylindrical chamber to force the metallic particles to move to the collector. The device is provided with air ducts having nozzles for supplying air in the tangential direction and toward the center of the closed cylindrical chamber. ^ EFFECT: enhanced efficiency. ^ 4 dwg
