摘要：
In this study, the influences of microwave irradiation on the dissociation behavior and structural characterization of ilmenite ore were systematically investigated. The crystal structures, microstructure, and surface chemical functional groups of the samples were characterized before and after microwave irradiation using X-ray diffraction (XRD), scanning electron microscopy (SEM) and Fourier transform infrared (FT-IR), respectively. Treatment variables, microwave power and exposure time, had statistically significant effects on the dissociation behavior and structural characterization of ilmenite ore. The XRD, SEM and FT-IR analysis results indicated that the crystal structures, microstructure, and surface chemical functional groups of microwave treated ilmenite ore are better than those of ilmenite ore.
