The analysis of mineralogical characteristics has important significance in comprehensive utilization of polymetallic sulphide mineral resources. The wavelength dispersive X-ray fluorescence (WDXRF) and X-ray diffraction were performed for the standardless quantitative analysis of Ni/Cu polymetallic sulphide ore collected from Sinkiang, China. On the basis of fundamental parameter approach and Rietveld refinement Method, the validity of mineralogical identification and quantification was confirmed for analyzing this complex sulphide ore. The results of XRD-Rietveld method were in good agreement with elemental concentrations determined by XRF and ICP, which has explained the subtle differences among four samples in the range of different granularity (>10mm; 6-10mm; 1-6mm; <1mm;). And the thermogravimetric curves and magnetic hysteresis curves, as well as element distribution map characterized by SEM-EDS, shown tiny differences among four samples. These results indicate that quantitative phase analysis using the Rietveld method represents a new powerful and fast tool in studies of the complex sulfide deposit.
