The production of aluminum metal is initially chemical. That is, the sodium chemistry method founded by the French scientist H. Sainte Claire Diwill in 1854 and the magnesium method founded by the Russian physical chemist HH Becketov (1.Ð.Бекетов) in 1865. Chemical law. France began industrial production in 1855 using chemical methods and was the first country in the world to produce aluminum.
The discovery of bauxite (1821) was earlier than aluminum and was mistaken for a new mineral. To produce aluminum from bauxite, it is first necessary to prepare alumina and then electrolyze it to produce aluminum. The mining of bauxite began in France in 1873. The alumina production from bauxite began in 1894 with the Bayer process and the production scale was only over 1 day per day.
By 1900, a small amount of bauxite was mined in countries such as France, Italy and the United States, with an annual output of only 90,000 tons. With the development of modern industry, aluminum was applied as a metal and alloy to the aviation and military industries, and then expanded to the civilian industry. Since then, the aluminum industry has developed rapidly. By 1950, the world's metal aluminum production had reached 1.51 million tons. 1996 increased to 20.92 million t, only to become the second most important metal steel iron.
The general exploration work of bauxite mines in China began in 1924. At that time, the Japanese man, Sakamoto Junxiong, conducted a geological survey on the shale shale in Liaoyang, Liaoning Province and Yantai, Shandong Province. Since then, Japanese Xiao Guanyi and others, as well as Chinese scholars Wang Zhuquan, Xie Jiarong, Chen Hongcheng, etc. have successively visited Shandong Zibo, Hebei Tangshan and Kailuan areas, Shanxi Taiyuan, Xishan and Yangquan areas, Liaoning Benxi and Fuzhou Bay areas. Special geological surveys were carried out on soil and bauxite shale. The investigation of bauxite in southern China began in 1940. First, Bian Zhaoxiang investigated the bauxite mine near Banqiao Town, Kunming, Yunnan. Subsequently, from 1942 to 1945, Peng Qirui, Xie Jiarong, Le Sen Wang Xun and others conducted geological surveys and systematic sampling of bauxite and high alumina clay mines in Yunnan, Guizhou and Sichuan. In summary, the work before the founding of New China was mostly of a general nature of investigation and investigation.
The true geological exploration of bauxite began after the founding of New China. Between 1953 and 1955, the geological team of the Ministry of Metallurgy and the Ministry of Geology successively applied aluminum to the Shandong Zibo bauxite mine, the Xiaoguan area of ​​Gongxian County, Henan Province (such as Zhulingou, Chadian, Shuitou and Zhongling), and the Guizhou area. Soil mines (such as Linxi, Xiaobaba, Yanzi and other mining areas), Shanxi Yangquan Baijiazhuang mining area, etc., carried out geological exploration work. However, at that time, due to the lack of exploration experience of bauxite, the bauxite specifications of the former Soviet Union were blindly applied in combination with the actual situation of Chinese bauxite. As a result, most of the geological exploration reports were downgraded during the review from 1960 to 1962. The reserves have also been reduced a lot. After 1958, China's bauxite exploration of accumulated some experience, based on census vigorously copper aluminum, also found a lot of exploration and mining, one of the more important are: Henan Zhang Kiln House, Pingguo , Shanxi Xiaoyi Ke Russia, Fujian Zhangpu, Hainan Penglai, and other bauxite mining areas.
The mining of bauxite in China began in 1911. At that time, the Japanese first exploited the bauxite mine in Fuzhou Bay, Liaoning Province, China. From 1925 to 1941, it was on the two floors of A and G in Liaoyang, Liaoning Province, Yantai, Shandong Province. Bauxite is mined and the above mining is mostly used as refractory material. From 1941 to 1943, the Japanese exploited the Tianzhuang and Hongtupo sections of the Hutian and Minshui mining areas in Zibo Bauxite Mine in Shandong Province, China, and the ore was used as raw material for aluminum smelting. Later, Taiwan Aluminum Corporation also conducted small-scale mining for aluminum smelting.
The large-scale development and utilization of bauxite in China began after the new China. In 1954, the Shandong Lishui mine, which had been mined by the Japanese before, was first restored. After 1958, 501, 502, and 503 three aluminum plants were built in Shandong, Henan, Guizhou and other provinces. In order to meet the demand for bauxite in these three aluminum plants, they were built in Shandong, Henan, Shanxi, Guizhou and other provinces. Zhangdian Aluminum Mine, Xiaoguan Aluminum Mine, Luoyang Aluminum Mine, Xiuwen Aluminum Mine, Qingzhen Aluminum Mine, Yangquan Aluminum Mine and other aluminum ore raw material bases.
In the 1980s, especially after the establishment of China Nonferrous Metals Industry Corporation in 1983, the geological exploration and aluminum industry of China's bauxite mines developed rapidly, and a large number of large and large enterprises represented by Shanxi Aluminum Plant and Zhongzhou Aluminum Plant were newly built and expanded. The aluminum plant has increased the production of primary aluminum in China from less than 2,000 tons in 1954 to 1.87 million tons. A complete set of aluminum industrial system from geological, mining to smelting and processing has been established. Aluminum metal and its processed products can basically meet the needs of China's economic construction.
