Separating P2O5 from steelmaking slag is the key to achieving optimum resource utilization of slag. If P-concentrating 2CaO?SiO2–3CaO?P2O5 solid solution was effectively separated, it can be a potential phosphate and remaining rich in Fe2O3 CaO reutilized as flux process. In this study, low-cost method selective leaching adopted, hydrochloric acid selected agent. The dissolution behavior quench...

The electric arc furnace (EAF) has the potential to significantly contribute decarbonization of iron and steel industry. However, during EAF steelmaking, carbon still needs be injected into molten slag initiate foaming, which is beneficial energy efficiency protection furnace. To move away from fossil carbon, biocarbon gained attention as an injection agent. In this study, two biochar candidate...
