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 Portland ciment production. Characterization of mixed waste of granite and LD aciariw. With this new process it was possible to obtain two solid parts: Bassi, Mara da Rocha Published: Souza, Ticiane Vieira de Paula.

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.

Samples cooled in water, after examining with X-ray difractrograms, had been predominantly amorphous.

Klug, Jeferson Leandro Format: The adjustment of the chemical composition of the slag from steel works by the addition of waste granite was efficient, transforming the waste into caiaria product that is the same as blast furnace slag and can be used in the manufacture of cement. How to cite this article. LD of steelworks slag; residue of granite; Portland cement.

Metallurgical slags have been studied and should be considered as subproducts of the steel industry with economic value. Dayrell, Fernanda de Oliveira Published: The following techniques where used: Polisseni, Antonio Eduardo Published: LD BOS slags contain high content of iron oxide because they are produced in oxidant aciariia, and due to this fact these particular slags are not suitable for Portland ciment p This study focuses on the technical feasibility of the utilization of waste from the cutting of granite to adjust the chemical composition of slag from steelworks LD, targeting the addition of clinker Portland cement.

We selected samples of the waste, mixed, melted and cooled in water and in the oven.

It is concluded from this study that the separating iron oxides methodology proposed is promising for treatment of LD slags the present study can be used as a reference for separating iron oxides from white oxides of BOS slag which was treated by the BSSF process. Services on Demand Journal.

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.
