Abstract：The basic physical and chemical properties of electric arc furnace (EAF) dust containing high content iron were tested priority during the solid waste identification. The main components and mass fractions were identified by X-ray fluorescence spectrometry (XRF). The main phase composition was obtained by means of X-ray diffraction (XRD) and mineral phase microscope technology. When the basic physical and chemical properties of imported material were same to the EAF dust containing high content iron, the characteristic physical and chemical properties would be analyzed. The existent morphology of iron and iron oxide was determined by mineral phase microscope technology. The micro morphology and particle size distribution of imported material was revealed by scanning electron microscope and laser particle size analyzer. If at least one characteristic physical and chemical property was the same as that of the EAF dust containing high content iron, the source of the imported material could be determined as the EAF dust containing high content iron. Finally, the solid waste identification conclusion of the imported material was obtained according to the Identification standards for solid wastes guide General rules (GB 34330—2017). The three characteristic physical and chemical properties and the process of solid waste identification of imported EAF dust containing high content iron were pointed out. It would provide technical reference for supervising and identifying the solid waste property of imported EAF dust materials, which had great significance for preventing the import of EAF dust materials containing high content iron.
