Hazard-Free Treatment and Reuse of Magnesium Slag
For magnesium slag samples subjected to high-temperature treatment, the F content is 54.1–163.0 mg/kg for the leachate from acid leaching solution and 4.9–74.6 mg/kg for leachate from neutral leach solution, the former higher than the latter. Thus, the acid leach solution can favor F leaching from magnesium slag.
