Causes and occurrence: graphite is formed at high temperatures. Is the most widely distributed graphite metamorphic deposits, rich in organic matter or by the Department of carbonaceous sedimentary rocks formed by regional metamorphism China: Lacey City, Shandong Province is one of the important producer of graphite, graphite, graphite proven reserves of 6,871,100 tons of milk prices now reserves 6,399,300 tons. Another one of Panshi origin is graphite, graphite reserves of 5,000,000 tons. World: the famous origin: New York Ticonderoga, Madagascar and Ceylon, Jixi City of Heilongjiang Liu Mao was the largest producer. No pure natural graphite, which often contain SiO2, Al2O3, FeO, CaO, P2O5, CuO and other impurities. These impurities often appear to quartz, pyrite, carbonate and other minerals form. Further graphite milk, water well, asphalt, CO2, H2, CH4, N2 and other gases parts. Therefore, the analysis of graphite, in addition to fixed carbon content was measured, it must also determine the content of volatile matter and ash simultaneously. Roughness graphite, graphite, carbon industry is provided by the North Sea Dragon Sea Dragon Carbon Co., Ltd. Weifang. Carbon Co., Ltd.
