FIELD: mining.
SUBSTANCE: present invention relates to the field of gravity concentration of fine ores different in density, in particular noble metal ores. The apparatus for gravity concentration of fine ores and noble metal processing products includes a conical rotor bowl, a power device, rich fraction, middling product, and tailing discharge devices. The internal surface of the conical rotor bowl has circular rifflings from the bowl bottom to a height of 0.9-0.92 H of the rotor bowl height, an adjustable circular slot widening to the discharge side being located at a height of 0.95 H, (H is the rotor bowl height).
EFFECT: increased recovery of valuable components from ore.
