FIELD: mining industry; devices for gravitational concentration of sands of placer deposits of gold; technogenious placers and tailing ponds. SUBSTANCE: proposed device includes chute and magnetic system located under it and magnetic field control unit located between chute and magnetic system. Magnetic field control unit is made in form of adapter plate with magnetoconducting inserts above poles of magnets of magnetic system and with magnetic flux control units located between magnetoconducting inserts having different poles. EFFECT: increased extraction of gold and other heavy minerals due to enhanced efficiency of magnetic flux control. 3 cl, 3 dwg |
