【摘要】 本文首次比较系统地测定了10多种硫化矿石矿样预氧化前后的吸氧速度、自热特征和着火点变化情况，指出了在实验室中测定硫化矿石的自燃倾向性时应同时测定矿样预氧化后的自燃倾向性，以便使研究结果更具实用性。更多还原

【Abstract】 The oxygen absorption rates, self-heating features and ignition points of more than ten sulfide oresamples before and after pre-oxidizing were systematically tested. It is pointed out that the spontaneous combustion potential of sulfide ore samples after pre-oxidizing should be tested slmultaneously with testing the potential ofsulfid ore in laboratory in order to achieve more reliable and practical conclusions of the spontaneous combustiontendency of the tested sulfide ores.更多还原
