青海某伟晶岩型锂铍矿工艺矿物学研究

Process Mineralogy of a Pegmatite Lithium Beryllium Ore in Qinghai

这是一篇工艺矿物学领域的论文。运用光学显微镜、化学多元素分析、化学物相分析、X射线衍射、扫描电镜—能谱仪等综合手段,对某伟晶岩型锂铍矿工艺矿物学特征展开研究。查明了矿石中矿物组成、化学性质、矿物的共生关系、主要矿物的粒度分布和连生特征等。在此基础上阐述了矿石中锂、铍等有价元素的赋存状态和影响矿石中锂、铍等有价元素回收的矿物学因素,为该矿的选矿工作提供了依据。

This is an eassay in the field of process mineralogy.Using optical microscope,chemical multi-element analysis,chemical phase analysis,X-ray diffraction,scanning electron microscopy-energy spectrometer and other comprehensive methods,the process mineralogical characteristics of a pegmatite lithium beryllium ore were studied.The mineral composition,chemical properties,symbiosis relationship of minerals,particle size distribution of main minerals and connection growth characteristics in the ore were ascertained.On this basis,the occurrence state of valuable elements such as lithium and beryllium in the ore and the mineralogical factors affecting the recovery of valuable elements such as lithium and beryllium in the ore are described,which provides a basis for the beneficiation work of the mine.
