Abstract: With the acceleration of global industrialization, the issue of carbon dioxide (CO 2 ) emissions has become increasingly severe, highlighting the urgent need to develop effective CO 2 capture and utilization technologies. CO 2 absorption-mineralization technology, as an emerging method, can convert CO 2 into solid minerals, achieving both long-term storage and emission reduction goals. This paper systematically reviews the latest research progress in CO 2 absorption-mineralization technology, with a particular focus on its application potential and sustainability in the steel industry. Additionally, it summarizes the research status and optimization strategies of various monoamine and mixed amine absorbents and explores the main process technologies, reaction mechanisms, and key parameters of industrial CO 2 mineralization. Through multiscale modeling analysis, the study delves into the reaction mechanisms and influencing factors of the mineralization process, providing theoretical support for the industrial application of the technology. The research indicates that CO 2 absorption-mineralization technology not only effectively reduces greenhouse gas emissions but also offers raw materials for industries such as construction, thus promoting sustainable resource development. Although this technology shows good application prospects, it still faces key challenges in economic viability and technical feasibility during practical implementation. This paper aims to clarify the current research hotspots and challenges, providing theoretical and practical support for future large-scale application.
