In this paper, the mineralogical characterization of typical copper slag supplied by the Tongling Nonferrous Metals Group China was performed based on x-ray fluorescence, x-ray diffraction, and scanning electron microscopy with energy dispersive spectroscopy. The results show that the dominant phases of the slag are fayalite, glassy substance and magnetite. The minor accessory phases consist of copper matte, metallic copper and other complex lead and zinc minerals. The contents of iron, copper, lead and zinc in copper slag are 40.21%, 0.79%, 0.24%, and 2.80%, respectively. The mineralogy of copper slag indicates that these valuable elements are difficult to recover by beneficiation processes due to the complicated occurrences. Instead, the pyro-metallurgical processes appear promising in recovering the valuable metals from copper slag.
