In the pursuit of sustainable solutions for carbon dioxide CO2 sequestration and emission reduction in steel industry, this study presents an innovative integration steelmaking slag with modified Solvay process sodium bicarbonate (NaHCO3) synthesis from saline brines. Utilizing diverse minerals, including electric arc furnace (EAF) slag, olivine, kimberlite, explored their reactivity under varied pH conditions examined potential ammonium regeneration. Advanced techniques such as XRD ICP-OES were employed to meticulously analyze mineralogical transformations elemental concentrations. The findings demonstrate that owing its superior buffering capabilities, outperforms natural minerals. finer particles significantly elevated levels, facilitating efficient Geochemical modeling provided valuable insights into mineral stability which aligned results. This synergistic approach not only aids capture through carbonation but also minimizes waste, showcasing a environmentally responsible solution mitigation industry.
