Thermal methods of analysis such as DSC and TGA provide a powerful methodology for the study of solid reactions. This paper proposes an improved thermal analysis methodology for thermal stability and safety investigation of complex solid-state reactions. The proposed methodology is based on differential iso-conversional approach and involves peak separation and individual peak analysis for kinetic analysis and safety prediction. The proposed thermal analysis method was coupled with Mineral Libration Analysis (MLA) to investigate self-heating of sulfide mineral ores. The influence of sample's mineralogy on thermal degradation was examined and discussed. The information gained from the advanced kinetic analysis of DSC/TGA measurements were up-scaled for TMR and SADT determination. The described thermal analysis method provides not only an understanding of sulfide mineral self-heating, but also aids the design of effective mitigation measures for their adverse environmental and safety effects. © 2011 Akadémiai Kiadó, Budapest, Hungary.
