The main factors affecting the oxidation and spontaneous heating of sulfide ores are discussed in this paper, including the crystal structure, trace metal content, environmental temperature, oxygen concentration, moisture, particle size, environmental pH value, ferric iron, bacteria, among others. It is shown that the reaction modes of sulfide ores at ambient temperature are complex; the oxidation and self-heating are influenced by many factors; an increase in temperature and oxygen concentration has an increasing effect on the oxidation and self-heating; the reactivity increases as the particle size decreases; both ferric iron and bacteria act as catalysts in the oxidation; water has effects on both the oxidation and self-heating; whereas neither crystal structure nor trace metal content has a consistent effect on the oxidation rate., authors=null, authorsList=null,

articleAbstract=堆积在采场环境中的硫化矿石容易发生氧化自热，从而造成环境污染、导致矿石结块，甚至引发矿山内因火灾事故。系统阐述了硫化矿物的晶体结构、痕量元素的含量、环境温度、铁离子、氧气浓度、空气湿度、矿石含水率、矿样的粒度分布、环境的pH值、微生物等主要因素对采场中硫化矿石氧化自热的影响。结果表明，硫化矿石在低温环境中的反应模式非常复杂，其氧化自热受诸多因素共同影响；较高的环境温度和氧气浓度有利于矿石氧化，矿样粒度越小越容易自热，铁离子与细菌对硫化矿石的氧化具有催化作用，水对矿石的氧化自热具有催化和阻化两重作用，而晶体结构、痕量元素含量的影响均表现出不确定性。,
