- •
Serpentine is partially dehydrated and converted to olivine by intensive dry grinding.
- •
Serpentine content enhances the formation of new surface during mechanical activation.
- •
Serpentine content reduces the disorder of microstructure in olivine during grinding.
- •
3600 kW h/t energy input can improve the carbonation conversion from 8.7% to 31.7%.
