· Steelmaking slag contains around 10 % of scrap which comes from the refining process or from some of the processing vessel ( BOF, EAF, steel teeming ladle, or tundish). It is advantageous to separate this scrap from the slag for the purpose of recycling the recovered scrap in the primary steelmaking process for making the slag free from scrap for its various appliions.
