Abstract：X-ray fluorescence spectrometry (XRF), infrared spectroscopy (IR) and polarizing microscopy (PM) were applied to identify copper concentrates and solid wastes of matte residue and anode furnace slag produced in the copper smelting process. XRF, IR and PM were used to characterize elemental composition, gangue minerals, and non-gangue minerals, respectively. With the three methods combined, the phases could be indentified. The results showed that there was no overlapping in phase composition of copper concentrate, matte residue and anode furnace slag, and phase retrieval could be accurately determined through phase analysis, so that copper concentrate and solid waste produced in smelting process could be identified effectively.
