FIELD: technological processes.
SUBSTANCE: method for integrated processing of man-made and complex iron-bearing raw materials includes grinding, magnetic separation and classification. The raw material is additionally grinded and subjected to magnetic separation in weak magnetic field. The weak magnetic product is finely ground and directed to magnetic separation in strong field. The non-magnetic product in the form of tails is sent to a tailings pond. The magnetic product is sent to hydraulic classification, the discharge is subjected to fine screening, the sublattice pulp is subjected to ultrasonic treatment with simultaneous aeration of the pulp with air. Then the pulp is thickened, filtered, dried, and a strong magnetic product, hydraulic classification sands and take-off product of fine screening are sintered and directed to metallurgical processing.
EFFECT: production from low-quality, complex raw materials and actual waste products, in demand both in metallurgical and paint and varnish industries.
