Abstract 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.
