Four natural flake graphite industrial bases in China

The production of natural flake graphite is abundant in the world, especially in China, and several producing areas in China produce a large amount of graphite.

China is rich in graphite resources, with the total reserves ranking the first in the world for a long time, including more than 1 billion tons of crystalline graphite. The scale of crystalline graphite ore is mostly large and medium-sized, accounting for 70% of the total number of ore-producing areas. About 88% of the mineral reserves of crystalline graphite in China are concentrated in large-scale ores.

Graphite resources are widely distributed in China. At present, 91 mining areas have been found in 25 provinces (cities, autonomous regions). From the national perspective, the distribution of graphite resources is characterized by “wide distribution, more in the East and less in the west, and individual enrichment”. Crystalline graphite is mainly distributed in Heilongjiang, Inner Mongolia, Shanxi, Sichuan, and Shandong provinces, with more than 80% reserves in China. Heilongjiang and Inner Mongolia have the largest reserves of crystalline graphite; aphanitic graphite is mainly distributed in Inner Mongolia and Hunan Province, and its reserves account for more than 67% of the country.

Since 2015, great achievements have been made in the exploration of large and super large graphite deposits in China. For example, the amount of proven graphite minerals in the northwest Leng Graphite Deposit in Linkou, Heilongjiang Province, has reached more than 35 million tons, reaching a super large scale; Dawudian Graphite Deposit in Wulate Middle Banner, Inner Mongolia, has proved 17.76 million tons of crystalline graphite minerals, reaching a super large scale; More than 7 million tons of crystalline graphite minerals have been discovered in chahanmuhulu Graphite Deposit, Alxa Right Banner, Inner Mongolia, reaching a super large scale.

Property The main producing areas of aphanitic graphite are Chenzhou, Hunan, Panshi, Jilin, etc.

4.Inner Mongolia Xinghe

Xinghe County of Inner Mongolia is rich in graphite resources, especially flake graphite. The proven ore reserves are 65 million tons and the prospective reserves are 200 million tons. It is one of the three major graphite-producing areas in China. Due to its excellent properties, high-temperature resistance, acid and alkali resistance, corrosion resistance, wear resistance, compression resistance, and conductivity, flake graphite is widely used in iron and steel, machinery, metallurgy, refractory, chemical industry, new electronic industry, and other industries.

With the development of China’s natural graphite industry standardization, the production cost of primary products increases, coupled with the strict environmental inspection, the production of deep-processing products is limited, especially the graphite purification link, which has become a bottleneck restricting the development of natural graphite industry in some places. Therefore, there is more and more imported natural graphite in China’s natural graphite market, and domestic natural graphite enterprises begin to purchase overseas graphite powder in batches, or directly open overseas graphite mines.

But in recent years, more and more companies have begun to process flake graphite, and the output and quality of flake graphite vary from place to place, but after factory processing, both ultra-fine flake graphite and large flake graphite can meet customer standards.
