FIELD: mineral dressing.
SUBSTANCE: invention concerns production of iron-titanium-vanadium concentrates from corresponding complex ores for subsequent metallurgical processing. Method comprises crushing original ores followed by dry magnetic separation. Crushing involves opening of combined junctions of titanium-magnetite-ilmenite with silicate minerals and is carried out to achieve fineness from 50 to 15 mm. Dry magnetic separation is effected at magnetic field intensity 40 to 120 kA/m, specific productivity from 50 to 100 t/h per 1 m length of magnetic separator drum, and moisture of ore being concentrated from 3 to 5% resulting in isolation of combined titanium-magnetite-ilmenite concentrate into magnetic fraction for succeeding smelting to produce vanadium-containing cast iron and high-titanium slags for production of titanium dioxide.
EFFECT: enhanced process efficiency.
