- •
HA inhibits the leaching concentration for some elements by complexes −coprecipitation.
- •
High concentration of HA could affect the formation of gismondine obtained from FA hydration process.
- •
Free-CaO is the most critical factor influencing the adsorption performance and leaching behavior of FA.
- •
Adding CaO could increase the types of hydration products, which maybe inhibit the leaching of some elements from FA.
