摘  要:依据铝工业生产国际实践经验,参考国内相关法规规范,针对某铝土矿开发利用企业开展放射性特征研究。通过对采矿、选矿、氧化铝生产工艺环节现场踏勘测量、取样分析测试,系统分析评估放射性特征,明确放射性关注环节及影响程度,提出针对性防护措施及建议。采矿、选矿、氧化铝生产环节放射性水平总体正常,但赤泥等放射性水平相对较高。防护措施主要包括工作人员防护、矿石运输、废水处理等。According to the practical experience of international aluminum industry,radioactive impact effect bauxite utilization was studied by referring to the relevant laws and regulations of China.Through site reconnaissance,survey and sampling analysis in mining,mineral processing and alumina production,the radioactive characteristics were evaluated,targeted protection measures and suggestions were proposed.The radioactive level in mining engineering,mineral processing and alumina production were normal overall,while the radioactive level of red mud was relatively high.Protection measures for the bauxite utilization should mainly include staff protection,ore transportation,wastewater treatment,etc.
