FIELD: metallurgy. ^ SUBSTANCE: invention relates to ferrous metallurgy field, particularly to reprocessing of metallurgical slag, used in building industry, particularly in highway engineering, in concreting and others, to receiving or enrichment of magnetic iron-containing product, used in blast-furnace melting for changing of iron-ore raw material, in melting of steel and at manufacturing of agglomeration. ^ EFFECT: invention provides total reprocessing of running and blade blast-furnace and steelmaking slag, including low-enriched blade nonstandard magnetic product, with receiving of cheap iron-ore raw material with qualitative characteristic, high-grade breakstone of fractions 5-10 mm, 10-20 mm, or mixture of fractions 5-20 mm, 20-40 mm, 40-70 mm, and sand of fraction 0-5 mm. ^ 5 cl, 2 dwg, 2 ex |
