试析淮北矿区共伴生硬质高岭土矿矿物特征

在系统搜集淮北矿区勘探和生产中揭露的共伴生硬质高岭土取样化验及测试资料的基础上 ,通过矿区基本化学分析、X衍射、电镜分析、差热分析等 ,并结合肉眼观察 ,分析研究了高岭土的矿石类型、化学成份、矿物特征 ,初步划分了矿石的自然类型与工业品级。确认该区硬质高岭土矿石中高岭石矿物含量大于 90 %以上 ,得出菱铁矿鲕粒含量多少是制约矿体赋存的重要因素之一 ,并决定着高岭土矿床的开采工业价值 ,对以后勘探、开采利用具有一定的指导意义

Analysis of the Mineral Feature of Associated Hard Kaolin of Huaibei Mine area

Based on the sample analysis of associated hard kaolin, exposed during exploration and production, together with the test data obtained, after elementary chemistry analysis, X-diffraction, electron microscope analysis, differential thermal analysis and naked eye observation, the ore type, chemical ingredients and mineral features of kaolin are studied. The natural type and industrial grade of the ore are categorized. This paper confirms that the content of kaolinite is over 90% in the kaolin ore and concludes that the content of siderite is one of the major factors that set constraints on the orebody host and industrial value . The conclusion is of significance for exploration and mining in future .
