FIELD: process engineering. ^ SUBSTANCE: invention relates to dressing of minerals containing fine gold. Centrifugal concentrator comprises receiving bin, working member made up of rotary perforated encased cup, central bearing tube, discharge flute to discharge tails, device to discharge dressed concentrate, and drive. It comprises also bearing frame, clarified water radial deflector provided with safety replaceable coarse screen arranged inside perforated cup to flow over clarified water in to said central bearing tube, centrifugal vaned pump to feed clarified loosening water. Pump drive shaft is coupled with perforated cup running in bearings of central bearing tube. Tube bottom is provided with openings for centrifugal pump. Receiving bin is equipped with distribution pipes that allow uniform feed of initial liquefied material in working zone, and arranged above radial deflector. Concentrate discharger is arranged inside central bearing tube. ^ EFFECT: higher efficiency of dressing. ^ 1 dwg |
