摘　　要：本文以贵州织金地区中低品位含稀土磷块岩为研究对象,分别研究了磷块岩的化学组分、稀土元素的分布、矿石的扫描电镜及显微镜下矿石的结构分析。结论为矿物的物质组成为碳氟磷灰石、白云石和石英为主,含有少量方解石、黄铁矿和粘土矿物,原生矿中P2O5一般在10.01%~19.90%,Si O2为19.05%~60.29%,CaO为20.75%~33.13%。稀土元素主要以钇(Y_2O_3)、钕(Nd_2O_3)、镧(La_2O_3)、铈(CeO_2)等四种元素为主,占稀土总量13.53%~34.90%。通过综合分析测试,查明矿石的矿物组成、稀土元素的分布,为深入开展该类型磷块岩矿物加工工艺提供基础资料。On this paper, the samples taken from Xinhua phosphorite,which is a most important phosphor and rare earth elements enriching zone in the western of Guizhou province. This study mainly analysed the chemical composition, the distribution of rare earth elements, the SEM observation and Microscope test. The results show that the mineral composition of phosphor were francolite, dolomite, quartz, calcite, pyrite and clay mineral. The range P205 grade of raw ore from 10.01% - 19.90%, SiO2 19.05 % - 60.29 %, CaO 20.75 % - 33.13 %. The REE in the ore are mainly yttrium （Y2O3） , lanthanum （ La2O3） , neodymium （ Nd2O3 ） , and cerium （ CeO2 ） elements, which account for 13.53% - 34.90% of the total REE. The mineral composition of ore samples, REE occurrence were obtained through a comprehensive analysis and test providing a basic information for this type of phosphate rock to be processed.
