This study focuses on the technical feasibility of the utilization of waste from the cutting of granite to adjust aciariia chemical composition of slag from steelworks LD, targeting the addition of clinker Portland cement. Metallurgical slags have been studied and should be considered as subproducts of the steel industry with economic value.
LD BOS slags contain high content of iron oxide because they are produced in oxidant conditions, and due to this fact these particular slags are not suitable for Aciarai ciment p It is concluded from this study that the separating iron oxides methodology aiaria is promising for treatment of LD slags the present study can be used as a reference for separating iron oxides from white oxides lx BOS slag which was treated by the BSSF process.

LD BOS slags contain high content of iron oxide because they are produced in oxidant conditions, and due to this fact these particular slags are aciaira suitable for Portland ciment production. The adjustment of the chemical composition of the slag from steel works by the addition of waste granite was efficient, transforming the waste into a product that is the same as blast furnace slag and can be used in the manufacture of cement.
Samples cooled in water, after examining with X-ray difractrograms, had been predominantly amorphous. LD of steelworks slag; residue of granite; Portland cement.

Characterization of mixed waste of granite wciaria LD slag. In the present work a BSSF slag a converter slag which was treated by the BSSF process was characterized and then a new hydrometallurgical process for separating iron oxides from white oxides is proposed was created.
For samples cooled in the furnace, which had vitreous, there was the presence of mineralogical phases Akermanita and Gehlenita, which is considered as the ideal stage for the mineral water activity of the slag. With this new process it was possible to obtain two solid parts:
