铜冶炼物料中铜的分析质量控制方法

Review on Analysis and Quality Control of Copper in Copper Smelting Materials

目前国内铜精矿供应紧俏,铜冶炼行业的原料复杂,有些偏离了认证和认可标准方法的样品,在检测时,用认证、认可文件不能很好地进行质量管控,需要对分析方法加以改进,从技术上进行管控。结合国内铜冶炼企业的实际情况和多年的实践经验,从样品的加工和保存环节、铜分析的技术环节、人员培训、质量抽查、定期开展质量分析会等方面对铜的分析质量控制进行了总结。在具体的质量控制中,针对铜冶炼行业成分复杂、易变化的物料分析,应根据实际情况进行质量管控,以提高铜分析的准确度。

At present,domestic copper concentrates supply is tight.The raw materials of the copper smelting are complex,and some samples deviate from the certification and accreditation standard methods.During testing,the quality control cannot be performed well by using the certification and approval documents.So,it is necessary to improve the analysis method and control it technically.Combined with the actual situation of domestic copper smelters and years of practical experience,the quality control of copper analysis was summarized from aspects of processing and preservation of samples,technical aspects of copper analysis,personnel training,quality sampling,and regular quality discussing meetings.In specific quality control,quality control should be carried out according to the actual situation to improve the accuracy of copper analysis for material analysis with complex and changeable composition in the copper smelting industry.
