This study investigates the effect of different temperature parameters on the CO2 mineralization process of Electric Arc Furnace (EAF) slag, aiming to enhance both conversion efficiency and the stability of formed carbonate minerals. The research focuses on optimizing temperature conditions to maximize CO2 uptake and improve the quality of mineralized products. Results from Energy-Dispersive X-ray Spectroscopy (EDX) analysis reveal a positive correlation between increasing temperatures and CO₂ conversion efficiency, with higher temperatures promoting enhanced carbonation reactions. These findings suggest that temperature control is a critical factor in optimizing the mineralization process, offering potential improvements in both environmental impact and material performance.
