Basic Oxygen Steelmaking Slag: Formation, Reaction, and …
Basic oxygen steelmaking (BOS) slag, a product of hot metal element (e.g., Si, Mn, Fe, P) oxidation and flux (e.g. lime, dolomite) dissolution, plays a critical role in the production of high-quality crude steel, although its behavior inside the BOS vessel (formation and reaction with metal droplets and gas) is still not clear and its recycling has always been challenging.

Mineralogy of Metallurgical Slags
In modern ferrous metallurgy, there are two main routes for steel production: the primary route converts iron ore via blast furnaces (BF) into pig iron, and pig iron via the BOF process into steel.The secondary route converts scrap via the electric arc furnace (EAF) into steel. The BF-BOF route contributes to 60% and the EAF route to …
