Abstract

Method of benefiting waste slag, originating from the production of oxygen steel (LD slag), characterized in that - said method comprising reduced to metal oxides present in the slag, by means of a reducing agent and with the addition of an additive that contains Al2O3, and separate iron from slag - to LD slag one or more additives containing at least the aluminum and silicon oxides are previously incorporated into it, said additive or additive being used in a ratio of 45-2.5 parts of additive per 55-97.5 parts of LD slag, and carbon as a reducing agent, and because the reduction takes place substantially in the solid phase, after which the iron is separated between about 1,250ºC and 1,500ºC from the newly formed slag and subsequently removed.
