摘　　要：Large amounts of steel slag(SS)and CO_(2)are produced globally each year during steel production.An SS-based carbon capture and utilization(SS-CCU)process for CO_(2)mineralization is suitable specifically for steel-making industries for simultaneous mitigation of CO_(2)emissions and valorization of wastes.However,the SS-CCU process is currently in the stage of laboratory research and far away from industrial application.In this review,some SS-CCU processes,including direct and indirect carbonation processes,were explored and summarized.Herein,the key factors and mechanisms of the SS-based CO_(2)sequestration process were identified.The carbonation process efficacy and its environmental impact(including global warming,energy use,water use,and metallic pollutants)were evaluated.Furthermore,the challenges and prospects of the further development of the SS-CCU process were discussed.
