devices applicable in concentration of ores of noble metals including platinum, containing magnetic fraction. SUBSTANCE: centrifugal concentrator has rotating bowl with accumulating grooves, branch pipe supplying initial raw material to bowl bottom and discharge device. Installed immovably in concentrator is multipole magnetic system with magnetic circuit embracing the supplying branch pipe. Located between magnetic system and bowl internal surface is concrete separating partition secured to bowl. External side of separating partition may have spiral groove. EFFECT: higher efficiency of concentrator due to continuous separation and withdrawal of magnetic fraction. 2 cl, 2 dwg
