METHOD OF MAGNETO-GRAVITATIONAL SEPARATION Russian patent published in 2002 - IPC

FIELD: concentration of minerals containing strong magnetic minerals, for example, magnetite or titanium-magnetite ores. SUBSTANCE: proposed method includes separation magnetite-containing mineral complexes in ascending water flows under action of variable field at frequency of 2 to 20 Hz and intensity of 4 to 16 kA/m exerted on ferrosuspension; frequency and intensity of magnetic field is decreased with increase of size of material being separated and rate of ascending flow is increased. EFFECT: improved quality of iron concentrate. 1 dwg, 2 tbl
