In order to explore the economic and comprehensive utilization of electrolytic manganese residue (EMR), the reaction kinetics of sodium carbonate roasting EMR were studied by using the model of flake structure minerals. The results showed that the initial roasting reaction was controlled by chemical reaction, while the middle and late reaction is controlled by diffusion. From the content of available silicon and the change node of the control type, the roasting reaction was basically completed in the initial stage. Therefore, chemical reaction control was the determining factor affecting the available silicon content in the process of sodium carbonate roasting EMR.
