Abstract: Based on the present research situation of spontaneous combustion for sulfide ores, the oxidation and self-heating mechanism were introduced systematically, including the physical mechanism, chemical thermodynamic mechanism, electrochemical mechanism, and bio-oxidation mechanism. The prediction and forecast techniques for spontaneous combustion of sulfide ores were put forward, such as spontaneous combustion tendency test, integrating all the relevant factors evaluation, statistic and empirical method, mathematical model prediction, forecast methods of significant gas analysis and temperature measuring. Moreover, the existing integrated control techniques for spontaneous combustion of sulfide ores were also summarized. In the end, the prospects over the future research on mechanism and control measures for spontaneous combustion of sulfide ores were set forth.
