## Description

- description: In this study, the chemical equilibrium experiments were systematically
    conducted at 1673 K under an oxygen partial pressure of 10-13 atm to investigate
    the precipitation of MnAl2O4 spinel in the CaO–SiO2–MgO–FeO–MnO–Al2O3 slags. The
    results showed that with increasing Al2O3 content, Mn gradually transferred from
    the silicate liquid phase into the spinel phase.
