摘　　要：现场冶金物料均采用送样定点检测的方法,检测数据时效性差、成本高。采用激光诱导击穿光谱(LIBS)技术对冰铜、尾料和铜精矿中关键元素的成分进行快速检测。结果表明:激光成分分析仪与X射线荧光光谱(XRF)分析仪的检测结果相比,Cu、Fe、SiO_(2)相对误差均小于8%,As、Sb的相对误差小于13%,LIBS与XRF的检测结果具有较好的一致性。通过激光诱导击穿光谱技术对铜物料成分的快速检测,提高了铜冶炼工艺调控的精准性,优化了生产成本,可为智慧冶金建设提供有力支撑。The on-site metallurgical materials are tested by sending samples at a fixed point,which has poor timeliness and high cost of detection data.The laser-induced breakdown spectroscopy(LIBS)technology was used to rapidly detect the components of key elements in matte,tailings and copper concentrates.The results show that compared with the detection results of X-ray fluorescence spectroscopy(XRF)analyzer,the relative errors of Cu,Fe and SiO_(2) tested by LIBS are all less than 8%,and the relative errors of As and Sb are less than 13%.The detection results of LIBS and XRF have a good consistency.Through the rapid detection of copper material composition by LIBS,the accuracy of copper smelting process regulation is improved,the production cost is optimized,and strong support is provided for intelligent metallurgical construction.
