The contents of different minerals in the ores were measured by both Thermogravimetric analysis (TG) and Differential Scanning Calorimetry analysis (DSC) at heating rates of 5, 10 and 15℃/min. The curves of TG, DTG and TG-DTG-DSC for each sample under different conditions were determined. Their combustion characteristic parameters were obtained, including the ignition points, temperature intervals of heat-absorption (radiation) and weight-gain (loss). The reaction activation energy for No. 1 and No. 2 samples was calculated by the Flynn-Wall-Ozawa method, with the results of 387.32 and 448.50 kJ/mol, respectively, which shows that a complement of TG method and DSC method is well achieved; the whole reaction process of sulfide ores can be reflected by their joint application; the gained activation energy can be used as indexes to evaluate spontaneous combustion tendency of sulfide ores under the condition of multiple samples being measured at the same time., authors=null, authorsList=null, authorCompany=null, correspAuthors=null,

articleAbstract=为了判定硫化矿石的自燃倾向性，对含有不同矿物成分的2种硫化矿样在升温速率分别为5，10和15℃/min条件下的氧化分解行为进行了热重和差示扫描量热联用分析，得到2种矿样在不同条件下的TG、DTG以及TG-DTG-DSC曲线，并获取其氧化燃烧过程中的特性参数，包括矿样的着火点温度，吸（放）热，以及增（失）重的温度区间等。运用Flynn-Wall-Ozawa法计算出2种矿样的反应活化能分别为387.32 和448.50 kJ·mol-1。结果表明，热重分析法和差示扫描量热分析法具有较好的互补性，联合应用在硫化矿石的氧化分解过程中能充分体现整个化学反应过程，在多样本条件下解算求得的活化能值可以作为判定其自燃倾向性大小的指标。, authors=阳富强^1,2，吴 超^1,2，石 英^1,2, authorsList=阳富强;吴 超;石 英;, authorCompany=1.
