This paper presents the results of the cadmium sulfide oxidation roasting process from the thermodynamic and kinetic aspect. Based on the known thermodynamic values for the reactions in the Cd - S – O system, phase stability diagrams were constructed. Kinetic investigations under the non-isothermal conditions have enabled the determination of the kinetic parameters. The experimental investigation utilized a sample of cadmium sulfide synthesized and prepared at the Department of Inorganic Chemical Technology in Plovdiv, Bulgaria. DTA analysis revealed four exothermal peaks within the temperature range from 753 K to 1073 K, while an increase above 1223 K led to one endothermal peak corresponding to the formation of cadmium sulfate dissociation into cadmium oxide. Kinetic analysis employing the H. E. Kissinger method allowed for the calculation of activation energy, illustrating that the processes occurring during cadmium sulfide oxidation lie within the kinetic domain. Overall, this research provides insight into the thermodynamic and kinetic characteristics important for understanding the cadmium sulfide oxidation process.
