FIELD: production of concentrates at concentration of metals; concentration of heavy minerals and metals contained in ore deposits of gold. SUBSTANCE: method includes wet screening on washing table by jet of water fed from hydraulic monitor, obtaining intermediate concentrate on deep filling sluice box combined with flat hydraulic screen and provided with hydraulic elevator and preparation of pulp directed to mechanical chute- shaped sluice box for heavy-medium concentration; it is mounted movably for motion in all directions in horizontal plane; each movable chute contains heavy medium which is liquefied by water fed from branch pipes found in wall and in bottom and directed to heavy medium, preparation of drainage on vibrosieve, final extraction of minerals in hydraulic tower containing heavy medium between two cylindrical surfaces which is liquefied by water fed from branch pipes found in walls and in bottom of hydraulic tower; pulp thus treated is drained into central pipe of hydraulic tower forming vortex eddy; concentrate thus obtained is drained regularly. EFFECT: enhanced efficiency of entrapping heavy thin particles. 3 cl, 1 dwg
