Experimental study of dissolution of minerals and CO2 sequestration in steel slag

This study strives to achieve a substantial amount of steel slag carbonation without using any harmful chemicals. For this purpose, experiments, were performed in an aqueous medium, in a semi-batch reactor, to investigate the effect of varying reaction conditions during the steel slag CO2 sequestration process. Further, studying the effect of dissolution on carbonation reactions and the mineralogical changes that subsequently occur within the slag helps provide insight into the parameters that ultimately have an impact on the carbonation rate as well the magnitude of the impact.
