FIELD: process engineering.
SUBSTANCE: invention relates to dry magnetic separation and may be used in mining, glass-work, chemical industry, etc. Proposed method comprises feeding initial submagnetic loose material along vertical magnetic system inducing magnetic field forces directed along normal to magnet working surface, separating said material into magnetic and nonmagnetic fractions and distributing separated product among appropriate bins. Product is fed in parallel flows along vertical zones of maximum magnetic force effects. Note here that every flow is forced through free fall deceleration device while magnetic fraction deposited on permanent magnet surfaces is forced vertically downward by means of vibrator.
EFFECT: higher efficiency of magnetic separation.
