In steel mills, iron ore goes through a preparation process, which includes pelletizing and sintering, where it is agglomerated into small pieces called "sinter" (Strezov et al. 2013). In addition, the iron ore undergoes pre-treatment to reduce the liquid raw iron's sulfur, phosphorus, and silicon content (Ballı and Sel 2023).
