Abstract：Based on the solid waste identification of three imported copper-containing materials,the solid waste identification method of copper-containing materials was obtained. The solid waste identification of copper-containing materials usually consists of three steps. The first step was to determine the natural properties of the material,including the use of the naked eye to observe the appearance and impurities. Semiquantitative analysis was performed using X-ray fluorescence spectrometry(XRF) to identify the main components and their mass fractions. The main phase composition of the material was obtained by means of X-ray diffraction(XRD) and mineral phase microscope technology. The scanning electron microscope(SEM) was used to analyze the micro morphology and particle size distribution of the very fine powder copper-containing materials. The second step was to determine the origin of the material. According to the material appearance characteristic and the test results,through the methods including the data comparison,the on-the-spot investigation and the expert consultation,the production process of the material was judged. It could be identified that the material was produced conscious or not. The third step was to determine the solid waste properties of the material. The solid waste identification conclusion was obtained according to the solid waste identification guide(Trial). The results showed that the three imported copper-containing materials were the copper slag produced in the copper smelting process,electroplating sludge,mixed material of slag/ash/secondary sludge from yellow copper scrap smelting process. The three copper-containing materials were all of nonimportation solid wastes. It would provide technical reference for supervising and identifying the solid waste property of imported copper-containing materials,which had great significance for preventing the import of copper-containing solid waste of copper slag,electroplating sludge,mixed material of slag/ash/secondary sludge.
