Dissolution of ferronickel slag depending on aging condition was studied. Ferronickel slag typically contains 54.05% SiO2, 34.33% MgO, and 5.51% Fe2O3. The main structure composite was similar to Enstatite [(Mg, Fe 2+) SiO3]. Ferronickel slag aging was made in 3 months under various experimental conditions, in water, bubbling water and wetting air. The most effective aging condition was the wetting air treatment. In this condition, the dissolving concentration of Mg and Fe was 80.0% and 75.1% respectively. The XRD and SEM data revealed that the wetting air condition also showed the biggest structural damage.
