以白钨盐酸分解渣作为研究对象，采用综合矿物分析系统(TIMA)、X射线荧光光谱仪(XRF)、X射线衍射(XRD)、扫描电镜(SEM)等方式分析了其化学成分、物相组成及主要矿物的赋存状态。结果表明：白钨盐酸分解渣中矿物颗粒呈自形-半自形-它形块状结构，其主要物相为钨酸、萤石、石英、锡石、黄铁矿、辉钼矿、毒砂、蓝铁矿，质量分数分别为66.93%、28.22%、1.12%、1.26%、0.3%、0.07%、0.2%、0.04%;钨酸嵌布粒度为110μm以上，而萤石、石英、锡石、黄铁矿、辉钼矿、毒砂矿石嵌布粒度主要集中在5～20μm之间，颗粒较细且与钨酸紧密镶嵌或被钨酸包裹。
Abstract：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.
