Graphite is an important non-metallic mineral resources. As a result of graphite's unique thermal conductivity and good chemical stability, corrosion resistance, radiation resistance, lubrication, and is widely used in machinery, metallurgy, petrochemical, light industry, electronics, electrical, defense, military, aerospace field. Graphite has become an indispensable material for high, new and sharp technical products in the contemporary world, from civilian use to atomic bombing, and to artificial satellites. Compared with its excellent properties, the special conditions of production make graphite become a valuable non-renewable resources. At present, the exploitation of graphite resources mainly concentrated in China, Brazil, India and a few countries, developed countries (such as the United States) also have graphite resources, but Europe and the United States developed graphite resources attach great importance to limit the exploitation of domestic graphite resources, China and other countries low-cost imports, and the implementation of reserves as a strategic material. With the development of science and technology, the application of graphite will be more and more widely in the economic development of the status of more and more important, graphite has become an important national strategic resources. China is a large country of graphite resources, its reserves, production, export volume ranking first in the world. China's graphite mining and processing enterprises about 100, many small and medium mining enterprises are disorderly predatory exploitation, most of the processing enterprises are also engaged in the production of primary raw materials, exports are basically low-priced primary products, a serious waste of resources , The economic and strategic value of resources should not be reflected.
Therefore, it is of great significance to analyze the status of graphite industry from the aspects of production, consumption and trade of graphite resources in the world, which is of great reference value to the development and rational utilization of graphite resources in China.


 World graphite resources:


The world's graphite deposits are dominated by medium and small deposits, which are mainly distributed in a few countries such as China, India, Mexico, Madagascar and Brazil. Graphite deposits can be roughly divided into the following types: 1, in volcanic rocks, siliceous sedimentary metamorphic rocks in the disseminated scale graphite deposits, the famous Madagascar crystal graphite ore is this type; 2, fracture filling cracks and cavernous vein Graphite deposits, a typical deposit is Sri Lanka vein graphite ore; 3, marble contact metasomatic or hydrothermal deposits in Russia and North Korea and other countries have distribution; 4, disseminated in the marble scale graphite deposits, Mexico, Most of India's graphite deposits and Australia's graphite deposits belong to this type.


The world's graphite mineral resources are mainly concentrated in China, the Czech Republic, Mexico, India, Brazil, Madagascar and Sri Lanka and other countries. With the United States Geological Survey statistics, in 2012 the world more than 77 million tons of graphite reserves.


Reserves:


China's graphite reserves and production are ranked first in the world. According to the Ministry of Land and Resources of China, China's crystalline graphite reserves of 30.68 million T, the basic reserves of 5235T, the resources of 17702 million T, 91 mining areas. Currently can be exploited about 60% of reserves. According to the order of reserves are as follows: Heilongjiang 1356 million T, Shandong 853 million T, Sichuan 233 million T, Inner Mongolia 272T, Henan 159T and so on.
