A brief introduction of the distribution of bauxite

The main component of bauxite is alumina, the hydrated alumina containing impurities, which is a mineral, shaped like earth, white or off-white, brownish yellow or reddish in color because of iron content. The density of it is 3.9 ~ 4g/cm3, hardness is 1 ~ 3, opaque, brittle, extremely difficult to melt, insoluble in water, but soluble in sulfuric acid, sodium hydroxide solution. Mainly used for aluminum smelting, refractory. Bauxite is the best raw material for producing metallic aluminum, and its significance will become evident. Of cause, bauxite also plays an important role in the metal mineral rights deal market, then what is the distribution of bauxite in China?

The distribution of bauxite inChinais highly concentrated. The bauxite in Shanxi, Guizhou, Henan and Guangxi province account for about 90.9% of that total in China (Shanxi: 41.6%, Guizhou: 17.1%, Henan: 16.7%, Guangxi: 15.5% ). The remaining fifteen provinces, autonomous regions and municipalities directly under the central government that own bauxite reserve together account for just 9.1% of the national total.

The bauxite in Shanxi is mainly distributed in Xiaoyi, Jiaokou, Fenyang, Yangquan, Yu county, Ningwu, Yuanping, Xing county, Baode, Pinglu that a total of five districts and 42 counties, an area of about 67,000 square kilometers, currently Shanxi proved bauxite reserves ranked first in the country, the total resources of the area is estimated to reach 2 billion tons. Currently the reserves of bauxite proved in Shanxi province ranked first in the country with an estimated about 2 billion tons.

Henan's bauxite is concentrated in the south of the Yellow River and west of the beijing-guangzhou line in more than 10 counties, including Gong county, Dengfeng, Yanshi, Xin 'an, Sanmenxia, Shan county, Baofeng, Lushan, Linru and Yu county. It has an area of more than 30,000 square kilometers, and the confirmed reserves of baucite are the second largest inChina, with a total estimated resource of 1 billion tons.

The bauxite deposite in Guizhou province are mainly distributed in more than ten counties, including Zunyi, Xifeng, Kaiyang, Weng'an, Zheng'an, Daozhen, Xiuwen, Qingzhen, Guiyang, Pingba, Zhijin, Goujiang and Huangping with an area of 2,400 square kilometers. Total resources are projected to exceed 1 billion tons.

Bauxite in Guangxi is concentrated in Pingguo, Tiandong, Tianyang, Debao, Jingxi, Gui county, Napo, Guohua, Long'an, Yongning, Chongzuo and other counties. The proved reserves of bauxite rank the 4th inChina, and the predicted reserves of bauxite are over 800 million tons.

Shandong's bauxite is mainly distributed in Zibo, Xintai, Hongshan and other counties, and its proved bauxite reserves account for 3% of the country's total reserves.

In addition, there are bauxite deposits in Hainan, Guangdong, Fujian, Yunnan, Jiangxi, Hubei, Hunan, Shaanxi, Sichuan, Xinjiang, Ningxia, Hebei and other provinces (regions).

In short,Chinahas rich bauxite resources, about 3.7 billion tons, rank forefront of the world.Chinawith guinea,Australia,Brazilare all the world's largest bauxite resources. How to reasonably exploit bauxite resources will become the pivotal problem which restricts the development of bauxite industry inChina.
