The iron and steel industry is energy-intensive, and steel slag and CO2 are the two major byproducts that accompany emissions during the smelting process. The use of steel slag for CO2 capture and utilization is a feasible and promising technology to achieve waste resource recycling. This paper firstly introduces the physicochemical properties of steel slag. The feasibility and potential application value of steel slag as a raw material for carbon capture are analyzed. Secondly, this paper discusses the existing process pathways for CO2 capture from steel slag and the factors affecting the carbon capture reaction. The reaction mechanisms of different steel slag carbon capture processes are analyzed. Finally, based on the current research status of steel slag carbonization technology, its development prospects and directions to be studied are proposed.
