| Abstract Scope |
Mineral carbonation has garnered significant attention as an effective carbon emission reduction strategy within the context of low-carbon development. This study investigated the synergistic coupling of multi-source alkaline solid wastes—including steel slag, tailings, and desulfurization ash—typical of the metallurgical industry, for enhanced carbon sequestration. Experimental results indicated that the carbonation degrees of steel slag and desulfurization ash individually reached 3.84% and 10.35%, respectively. However, when mixed in a 1:1 ratio, the blended solid waste achieved a carbonation degree of 20.76%. This enhancement can be attributed to the role of desulfurization ash in inhibiting surface passivation and expanding the reaction interface, as well as facilitating the dissolution of highly reactive calcium-bearing minerals through substitution reactions. This study explored the synergistic coupling of solid wastes to strengthen carbon sequestration, offering positive implications for the steel industry in terms of integrated waste mineralization and CO2 emission reduction. |
