Distribution of Graphite Minerals in China
The large and medium-sized graphite deposits discovered in the world are mainly distributed in China, India, Brazil, Czech Republic, Canada, Mexico and other countries. According to the US Geological Survey, the world's graphite reserves are 71 million tons, and China's graphite reserves are 55 million tons, accounting for 77% of the world. Brazilian graphite mines are distributed in Minas Gerais, Ceara and Bahia, and the best graphite is distributed in Paidrayajur, Minas Gerais ( Pedra Azul), the proven ore reserves are 250 million tons. Indian graphite mines are mainly distributed in the states of Orissa and Rajasthan. According to the "Annual Report of Indian Mining", India has 10.75 million tons of graphite reserves and 158.025 million tons of resources. Canadian graphite deposits are distributed in Ontario, British Columbia and Quebec. The Bissett Creek graphite deposit is the largest graphite deposit in North America. Sri Lanka's veined graphite deposits are world-famous and are the only highly graphitized veined graphite deposits in the world, located in the west and southwest of the island of Sri Lanka.
There are two types of graphite minerals in China: crystalline graphite and cryptocrystalline graphite. According to statistics from the Ministry of Land and Resources, as of the end of 2009, China's crystalline graphite mineral reserves were 30.41 million tons, the basic reserves were 54.32 million tons, and the resources were 13.54 million tons. In the past 20 years, my country's crystalline graphite reserves have been increasing, but the reserves of large-scale high-quality graphite have decreased to less than 5 million tons. Crystalline graphite is distributed in 20 provinces (autonomous regions) including Heilongjiang, Shandong and Inner Mongolia
Overview of mineral development
In 2010, the world's natural graphite production was 1.1 million tons. China's graphite production is 800,000 tons (crystalline graphite and cryptocrystalline graphite), accounting for 73% of the world's production. In the past 30 years, China's graphite output has ranked first in the world. In 1995, China's graphite production reached the highest level in history, at 2.215 million tons, of which 549,000 tons of crystalline graphite and 1.656 million tons of cryptocrystalline graphite. In 2008, China's crystalline graphite output hit a record high of 650,000 tons; in 2009, the output of crystalline graphite dropped to 480,000 tons, and the output of earthy graphite ore was about 1 million tons in the same period. China's crystalline graphite is developed in 16 provinces (autonomous regions) including Inner Mongolia, Heilongjiang, Shandong, Hebei, Henan, Hubei, and Sichuan. Important production areas are Jixi and Luobei in Heilongjiang, Pingdu and Laixi in Shandong, Xinghe in Inner Mongolia, Chicheng in Hebei, etc. Neixiang in Henan, Yichang in Hubei and Nanjiang in Sichuan. The development of cryptocrystalline graphite in China is mainly in the Chenzhou area of ​​Hunan Province and the Panshi area of ​​Jilin Province. There are many companies in the Chenzhou area of ​​Hunan Province that use ultra-high temperature technology to produce high-purity microcrystalline graphite.
