Mineralogical characteristics of gold in the Baolun gold deposit were investigated by using optical microscopy, X-ray diffraction (XRD) and electron probe microanalysis (EPMA) methods. The results showed that metal minerals in the ore were mainly pyrite and pyrrhotite, with minor amounts of chalcopyrite, sphalerite, arsenopyrite and galenite, while non-metal minerals were mainly quartz, calcite, and clay minerals. Gold occurred mainly as native gold, with a particle size ranging from 1 μm to 35 μm, and mainly in island-like, fine granular, and other irregular outlines.
