摘　　要：快速鉴别矿物元素的赋存状态,准确地选择适宜的处理工艺是推进冶炼企业持续发展的客观要求。传统物相分析方法检测铜精矿样品的流程烦琐,需要消耗较长时间,难以满足冶炼企业需求。采用X射线衍射法(X-Ray Diffraction,XRD)快速测定铜精矿样品,根据X射线衍射图谱确定不同进口铜精矿样品的物相组成及含量。X射线衍射仪的管电压为30 kV,管电流为20 mA。经试验验证,与国家标准物质测定结果对比,X射线衍射仪可以满足快速检测分析铜精矿物相的需求,方法适用性良好。Rapid identification of the occurrence status of mineral elements and accurate selection of appropriate processing techniques are objective requirements for promoting the sustainable development of smelting enterprises.The traditional phase analysis method for detecting copper concentrate samples is cumbersome and time-consuming,making it difficult to meet the needs of smelting enterprises.The copper concentrate samples are rapidly determined by using X-Ray Diffraction(XRD),and the phase composition and content of different imported copper concentrate samples are determined based on the X-ray diffraction pattern.The tube voltage of the X-ray diffractometer is 30 kV and the tube current is 20 mA.Through experimental verification,compared with the results of national standard substance determination,X-ray diffractometer can meet the needs of rapid detection and analysis of copper concentrate phases,and the method has good applicability.
