四川旺苍石墨矿工艺矿物学研究

对四川旺苍石墨矿进行了工艺矿物学研究，查明了矿区内矿石的化学成分、矿物组成、主要矿物的嵌布特征，并对石墨的晶体结构特征进行了测定。结果表明，矿石中石墨主要呈脉状或细脉状与石英、云母相间分布，部分呈自形或半自形散布在脉石矿物中，不同层位石墨粒度大小区别较大。固定碳含量为23.73%~47.41%。酸法纯化后样品的Raman光谱分析显示，石墨的ID/IG比值为0.02~0.07，说明各样品中不含非石墨结构的碳类物质，且石墨晶体结构缺陷较少、三维晶体结构发育完善。判定该矿区石墨为晶质鳞片状石墨，且不含隐晶质石墨。

Study on Process Mineralogy of Wangcang Graphite in Sichuan Province

The study on process mineralogical study was carried out on the Wangcang graphite mine in Sichuan province, identified the area chemical composition of graphite mineral, mineral composition and nesting characteristics, and the identification of crystal structure characteristics of the graphite. The results of process mineralogy show that the graphite is mainly distributed in veins or veinlets with quartz and mica phases, and some of them are self-shaped or semi-self-shaped scattered in gangue minerals, and the fixed carbon content was 23.73%~47.41%. Results of Raman spectroscopy analysis of graphite samples after the purification of acid method showed that the I_D/I_G ratio of each sample was 0.02~0.07. It shows that there are no carbon materials with non-graphite structure in each sample, as well as there are fewer defects in graphite crystal structure, and the three-dimensional crystal structure is well developed. Therefore, the graphite of the mine is determined to be a flake graphite with no cryptocrystalline graphite.
