The interface (gas-slag-metal) is of great significance to the removal of elements in the metallurgical process. In this work, the interfacial element distribution and structure of MnO-based slag with different compositions were explored using the gas-slag equilibrium experimental method and XPS detection method at the temperature of 1873 K. The result indicates that the proportion of non-bridged oxygen (O-) increased, while that of bridged oxygen (O0) decreased with the etching time increased regardless of different composition. Meantime, as the bacisity decreases, the bridged oxygen increases and the non-bridging oxygen decreases at the interface. Sulfur is enriched at the interface and decreases with the deepening of the etching depth. The gradient changes of the interface structure and elements prove the existence of the boundary layer, which has a guiding significance for the element removal process in the metallurgical process.
