The method of recycling secondary slag in the primary smelting of iron, the secondary slag is adjusted by the following steps - the cooling of the natural, demetallizing, the mechanical processing and sorting, in part densification to a compact form, the secondary slag with metallurgical ingredients are added as an additive to the initial melting in the mixture with addition of lime in a weight ratio of 1: 0.5 - 10, wherein the undersize fraction slag 0-12 mm is compacted to a compact form with the vibropressing in addition of 2-35% by weight of binder, and then dried for 5 hours up to 1-7 days in standard atmosphere depending on the binder which is Portland cement, molasses, lime, lime milk, magnesium cement, bentonite, respectively combinations thereof, or compacted to a compact form by pressing under high pressure such that the interrelationship of the particles occurs Van der Waals forces, and the oversize slag fraction 12-50 mm is used in the original condition without prior treatment. |
