摘要
进行含砷铁矿石脱砷研究对于有效开发利用我国贫矿、复合矿资源,降低钢材中砷质量分数有着重要意义。介绍了我国含砷铁矿资源的特点,综述了气化脱砷反应机理,铁矿石脱砷工艺以及温度、气氛、时间等因素对脱砷率的影响,展望了含砷铁矿石脱砷今后的研究方向及发展趋势。
Research on arsenic removal from arsenic-bearing iron ores is of great significance for better utilization of lean ores and complex ores and reducing the arsenic content of steel products in China. In this paper, the eharacteristics of arsenie-bearing iron ores of our country, the gasification reaction mechanism of arsenic removal, arsenic removal processes and factors to influence arsenie removal, such as temperature, atmosphere and time, are reviewed. In addition, the development direction of arsenic removal from arsenic bearing iron ores is also put forward in this paper.
