In recent years,there have been some cases of smuggling imported copper-containing waste using the name of copper concentrate.The traditional detection methods have certain limitations in the identification of such materials.In this paper,the attribute identification of one batch of imported copper-containing solid waste using the declared name of copper concentrate was studied by means of X-ray diffraction spectroscopy(XRD),X-ray fluorescence spectrometry(XRF),ultra depth of field microscopy,and scanning electron microscopy.The source of the samples was determined,which provided a scientific basis for the customs supervision and resource utilization.
