| Abstract (English): |
Guizhou's unique geographical location contains rich phosphate ore types. Mineral resources are consumed day by day, and the influence of poor grade on the production of wet-process phosphoric acid is becoming more and more serious. In order to improve the mineral processing technology, a special mineral processing method is developed for phosphate ores in this area. The process mineralogy of a mixed collophanite in Fuquan, Guizhou Province is studied by means of X-ray diffraction analysis, polarizing microscope, scanning electron microscope, energy spectrometer, chemical analysis and so on. The results show that the P2O5 grade of the phosphate ore is 26.16%, CaO/P2O5=1.54, and the industrial type of phosphate ore in this area is mixed type and mineral processing grade. The main minerals are fluoroapatite, dolomite, quartz, chalcedony, potash feldspar, albite, pyrite and clay. The MgO 90.32% to be removed from mixed collophane occurs in carbonate minerals, the SiO2 56.39% to be removed occurs in quartz and feldspar-clay minerals, the Fe2O3 79.21% to be removed occurs in iron-carbon minerals, and the Al2O3 44.61% to be removed occurs in carbonate minerals and feldspar-clay minerals. The distribution of harmful elements in each mineral is found out, and the study of monomer dissociation degree has a certain guiding significance for the mineral processing production.

| Abstract (Chinese): |
贵州独特的地理位置所蕴含的磷矿类型丰富。但矿产资源日益消耗, 品位贫瘠对湿法磷酸生产影响越趋严重, 为提升选矿技术, 针对该地区磷矿制定特有选矿方法, 对贵州福泉某混合型胶磷矿利用X射线衍射分析、偏光显微镜、扫描电子显微镜、能谱仪、化学分析检测等方法进行工艺矿物学研究。研究结果表明：该磷矿P2O5品位为26.16%, CaO/P2O5=1.54, 该地区的磷矿工业类型为混合型, 选矿加工级。主要矿物为碳氟磷灰石、白云石、石英、玉髓、钾长石、钠长石、黄铁矿和黏土类等, 均属细粒嵌布。混合型胶磷矿需要脱出的MgO 90.32%赋存于碳酸盐矿物中, 需要脱出的SiO2 56.39%赋存于石英质矿物、长石-黏土类矿物中, 需要脱出的Fe2O3 79.21%赋存于铁碳质矿物中, 需要脱出的Al2O3 44.61%赋存于碳酸盐矿物、长石-黏土类矿物中。查清了有害元素在各矿物中的分配情况, 结合单体解离度研究对该矿物选矿生产具有一定的指导意义。.
