“…X ray diffraction (XRD), pore structure analysis, scanning electron microscopy (SEM) and energy spectrometer (EDS) analysis are modern analytical methods, which are widely used in material preparation, nanomaterials and detection of bacterial pathogens [15][16][17]. In this study, in order to fully understand how the phase and structure changes of gangue minerals in carbonaceous gold ores during roasting affect the subsequent gold leaching, the oxidation of a fine-grained carbonaceous gold ore at various roasting temperatures was investigated using XRD, pore structure analysis, SEM and EDS analysis in conjunction with gold leaching tests.…”
