Supercritical CO2 coupled with mechanical force to enhance carbonation of fly ash and heavy metal solidification

[Display omitted] •Supercritical CO2 greatly promotes the carbonation of fly ash.•Compared with dry milling, wet milling has a better effect on carbonation improvement.•Supercritical carbonation has a significant inhibitory effect on heavy metals from fly ash. Accelerated carbonation of fly ash is a...
