摘要:
由于不同类型的硫化矿石氧化性不同,暴露在空气中的表面活性不同,其耗氧速率也不同。本文对几种硫化矿石矿样进行了程序升温氧化实验,获得了不同类型的硫化矿石矿样在氧化过程中的总吸氧量、自热起始温度与温度曲线。实验表明:硫化矿石氧化前期(矿样温度小于自热起始温度)氧化速度较慢,后期(矿样温度大于自热起始温度)氧化速度较快,说明当矿样温度加热到其自热起始温度以上时,矿样氧化放热量明显加大,加快了矿体的升温。
Abstract:
Both the surface activates exposed in air and their oxygen consumption rate are different due to the different oxidizability of sulfide ores. TPO experiments were conducted for sulfide ores samples. The total quantity of oxygen absorption,the self heating starting temperature and temperature curve were measured among the oxygenation of different sulfide ores samples. Experiment results showed that the sulfide ores oxidation rate was slower during the prior oxidation period, whereas oxidation rate was more quickly during the later oxidation period. It proved that when the temperature of the ores samples exceeded the self heating starting temperature, the ores samples oxidation output of the heat increased obviously, and quickened the ores heatingup.
