METHOD OF MAGNETIC SEPARATION AND DEVICE TO THIS END Russian patent published in 2012 - IPC B03C1/12 

FIELD: process engineering.

SUBSTANCE: invention relates to magnetic property separation of materials and may be used for extraction of highly magnetised materials from placer concentrates to be used in mining and lab conditions. Proposed method comprises forcing initial material through magnetic separator with cylindrical work surface with horizontal axis and variable, travelling, magnetic field, displacing flocculated magnetic particles by revolving drum and travelling magnetic field, separating material particles by magnetic forces, adhesion, friction as well as gravity and centrifugal forces into magnetic and nonmagnetic fractions, and discharging separation products. Magnetic fraction is subjected to continuous intensive cleaner flotation in forcing flocculated material along closed circular path over drum surface to separate joints and draw rock particles trapped in magnetic floccules, and periodic discharge of magnetic fraction after eliminating retaining magnetic field.

EFFECT: higher efficiency of magnetic separation and cleaning of highly magnetised impurities.
