FIELD: method and devices for concentration of dump waste products. SUBSTANCE: method includes mixing of solid substances with loosened heavy medium and discharge of concentrate through branch pipe of water ascending flow. The device has jigging machine with heavy suspension of natural minerals (magnetite, ilmenite, sulfides) in the form of wash pan on suspension secured to movable base and having hole in bottom, and unit for control of nine parameters. Loosening is effected by regulation of pressure in two coaxial branch pipes for supply of water in pan end walls and bottom. Light fraction is washed off by flow of transport water. Device has suspension with threaded appliance for regulation of angle of inclination of wash pan. EFFECT: production of concentrate of especially fine fractions of heavy minerals and their separation by specific gravity and sizes. 3 cl, 3 dwg
