AbstractSteelmaking slag mineral carbonation is a possible technology for the reduction of carbon dioxide (CO2) emissions to the atmosphere, which has been studied both in aqueous and dilute alkali medium. A set of variables, the stirring speed, reaction time, alkali to slag ratio and reaction temperature, were systematically investigated. The results indicated that reaction time, alkali to slag ratio and reaction temperature were the major factors for CO2 mineral sequestration. Under the optimal conditions with the alkali to slag ratio of 4 % at 80 degrees C, 16.64 g CO2 can be sequestrated in per 100g steel slag and both calcite and aragonite were generated. This work would be of significance to understand the reaction mechanism deeply and provide valuable information for further study in this field.
