摘　　要：为研究贵州织金地区某红土型锐钛矿矿石工艺性质,通过X射线衍射图谱分析(XRD)、X射线荧光光谱分析(XRF)、电感耦合等离子体制谱(ICP-MS)、显微镜镜下观察、扫描电镜配合能谱等,分别研究了矿石主要矿物成分、化学成分、微量元素和稀土元素地球化学特征、嵌布特征、元素赋存状态。研究表明,矿石中TiO_2含量为7.55%~8.59%,钛元素主要以锐钛矿独立矿物存在于矿石中;稀土元素含量偏高,属LREE富集,HREE亏损型;该矿石属于非均匀嵌布,细粒嵌布为主,粒度集中范围较窄应采用阶段磨矿,阶段选别流程。研究结果可为红土型锐钛矿资源合理开发利用提供依据。After field sampling of a red clay titaniumore in Zhijin, Guizhou Province, the ore sample was examined by chemical analysis, X ray diffraction analysis, observation under the microscope, scanning electron microscope and energy spectrum analysis. The main mineral composition, chemical composition, trace element and rare earth element geochemical characteristics, embedded feature, element occurrence state were studied respectively. Research shows that the TiO2 content in ore is 7.55%-8.59%, titanium elements mainly exist in the ore to anatase independent minerals; rare earth element content is high, LREE enrichment, HREE loss; the ore belongs to non uniformly embedded, fine disseminated, thegranularity should adopt the narrow range of stage grinding, stage separation process. The research results can provide the basis for the rational development and utilization of the red clay anatase resources.
