FIELD: enriching metals.
SUBSTANCE: sluice box comprises chute mounted for permitting vibration with respect to its longitudinal axis, fastening that allows the axis of vibration to be shifted below the center of mass of the chute under the load at a distance directly proportional to the specific weight of the material to be enriched, and catching surface with transverse baffles. The first half of the catching surface is provided with transverse grooves for catching finely divided particles of the heavy fraction . The transverse baffles are mounted on the second half of catching surface for catching large particles of the heavy fraction. The baffles are made under an angle to the direction of charging.
EFFECT: enhanced efficiency.
