Written by Howard Epstein, RVA 03 February 2014 Stainless steel slags generated in melting and refining operations are CaO-SiO 2-MgO rich with Cr 2 O 3, Al 2 O 3 and F- in minor quantities. A major issue is collapse of the slag structure on cooling as the high dicalcium silicate (C 2 S) content undergoes a phase transformation from β-C 2 S …
Mineral process wastes, such as metallurgical slags nowadays, are of significant metals and materials resources in the circular economy. The usability of iron-making slag is well established; however, steel slag still needs to be utilized due to various physicochemical constraints. In this context, we have reviewed the global steel slag …
