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.
