The chemical composition, phase composition, and occurrence state of the main minerals in scheelite hydrochloric acid decomposition residue were systematically studied by a comprehensive mineral analysis system (TIMA), X-ray fluorescence spectrometer (XRF), X-ray diffraction (XRD), scanning electron microscopy (SEM) and other methods. The results indicate that the mineral particles in the hydrochloric acid decomposition residue of scheelite exhibit euhedral to subhedral to anhedral blocky structures. The primary phases identified are tungstic acid, fluorite, quartz, cassiterite, pyrite, molybdenite, arsenopyrite, and vivianite, with their respective mass fractions being 66.93%, 28.22%, 1.12%, 1.26%, 0.3%, 0.07%, 0.2%, and 0.04%. The grain size of tungstic acid is above 110 μm, while the grain sizes of fluorite, quartz, cassiterite, pyrite, molybdenite, and arsenopyrite are mainly concentrated between 5~20 μm. These particles are relatively fine and are either closely intergrown with tungstic acid or encapsulated by it.
