As of the end of 1996, China has identified 222 molybdenum mining areas, distributed in 29 provinces, autonomous regions and municipalities. Molybdenum reserves reach 8.4200 million tons, of which A + B + C grade accounts for 39.8% of the reserves, which is 3.345 million tons. For example, compared with China ’s industrial reserves (A + B + C) and western countries ’reserve bases, China ’s Lower than the US 5.4 million tons, reserves basis), and higher than Chile (2.5 million tons, reserves basis), ranking second in the world
In terms of the distribution of molybdenum ore in China, Central and South China accounted for 35.7% of the country’s molybdenum reserves, ranking first. This was followed by 19.5% in the Northeast, 13.9% in the Northwest, and 12% in North China, while only 4% in the Southwest. In terms of provinces (regions), Henan has the largest reserves, accounting for 29.9% of the country ’s total molybdenum reserves, followed by Shaanxi with 13.6% and Jilin with 13%. In addition, provinces (regions) with large reserves are: Shandong accounts for 6.7%, Hebei accounts for 4%, Liaoning accounts for 3.7%, and Inner Mongolia accounts for 3.6%. The total reserves of the above 8 provinces (regions) accounted for 81.1% of the country’s total molybdenum reserves, of which the top three provinces of Henan, Shaanxi and Jilin accounted for 56.5%. Table 3.14.4 shows the main molybdenum deposits in China and their development and utilization.
Before the founding of the People’s Republic of China, except for the production of molybdenum from the Yangjiazhangzi Mining Bureau of Jinxi, Liaoning and the recovery of by-product molybdenum from a few tungsten mines in Jiangxi, there were very few molybdenum-producing mines. According to relevant statistics, the annual output of molybdenum concentrate in 1949 was nearly 1.4t. After more than 40 years of development, China has not only formed a large number of large-scale molybdenum industry bases, but also many copper, tungsten, tin mines have also recovered a large amount of by-product molybdenum. By 1996, China ’s molybdenum ore output reached 13.3782 million tons (including 9.498 million tons of directly-owned enterprises and 3.789 million tons of non-directly-owned enterprises), equivalent to 48,524 tons of metal (including 28.278 million tons of directly-owned enterprises and 20.24 million tons of non-directly-owned enterprises); The beneficiation and processing of ore is 14.397 million tons (including 10.63 million tons of directly-owned enterprises and 3.7.6 million tons of non-directly-owned enterprises) and 51961t of metal content (23465t of directly-owned enterprises and 28496t of non-directly-owned enterprises). In 1996, China’s output of molybdenum concentrate (45% of pure molybdenum) was 65,800 tons (mainly produced in Henan, Shaanxi, and Liaoning). In 1995, the output of molybdenum concentrates reached 73,300 tons. In 1995, the world ’s molybdenum concentrate output was 127,800 tons, of which 58,000 tons in the United States, 17,900 tons in Chile, and 8900 tons in Canada. The output of molybdenum concentrate in China is about 33,000 tons of pure molybdenum, ranking second in the world after the United States and before Chile. Table 3.14.13 lists the production of these products in the past 10 years.
There are many molybdenum concentrate mines in China. Among them, Jinduicheng in Shaanxi, Yangjiazhangzi in Liaoning and Luanchuan in Henan are three important molybdenum industry bases in China. Their production capacity accounts for more than 80% of the country’s total molybdenum concentrate output. In addition, mines such as the Baoshan lead-zinc-silver mine in Hunan and Shizhuyuan tungsten-tin-molybdenum-bismuth mine have also recovered a large number of molybdenum concentrates.
堆 Jinduicheng Molybdenum Industry Company is the largest molybdenum mining, processing and smelting joint enterprise in China, located in Huaxian, Shaanxi Province. The company was established in 1958. After nearly 40 years of transformation and development, it has now formed an annual output of 12,000 tons of molybdenum concentrate, 10,000 tons of molybdenum oxide, 350,000 tons of sulfur concentrates, 1000t of ammonium molybdate, 1500t of ferromolybdenum, The production capacity of copper concentrate is nearly 1000t. In 1996, 19556t of molybdenum concentrate (45% Mo) and 12898t of molybdenum oxide were produced.
Luoyang Luanchuan Molybdenum Company was established in 1972 and has developed into a large state-owned enterprise with one-stop production of mining, beneficiation, smelting and deep processing. The annual mining and dressing capacity is 1 million tons, the production of molybdenum concentrates is 4,000 tons, the smelting capacity is 3,000 tons, and the deep processing capacity is 150 tons. In 1996, the output of molybdenum concentrate was 4,717t, molybdenum 1096t, molybdenum powder 89t, and molybdenum bar 23t.
Yangjiazhangzi Mining Bureau is a production enterprise with a long history. It was put into production in 1899 and is still an important molybdenum production base in China. In 1995, the mining volume was 826,000 tons, and the mining volume was 25,500 m. In 1996, 2689 tons of molybdenum concentrate were produced.
In addition to these three major molybdenum industry bases, important molybdenum companies and mines include: Jinxi Molybdenum Company, Jilin Daheishan Molybdenum Mine, Chaoyang Xinhua Molybdenum Mine, Xiaosigou, Hebei and Xianlinbu Iron and Molybdenum Mine, and Huangshan, Qingtian and other molybdenum ore. Many copper mines, such as Dexing, Shouwangfen, Tongshan, Baoshan, and some tungsten mines also recover a certain amount of molybdenum.
Supply and demand situation
China’s domestic demand for molybdenum has been stable for a long time at the level of 4,000 to 5,000 tons (metal amount), at a level of about 10,000 tons. From the perspective of China’s current production capacity, there is more than enough self-sufficiency and the proportion of exports is relatively large.
In 1995, China exported 687,000 tons of molybdenum concentrates, 12,650 tons of iron molybdenum, 18,047 tons of molybdenum oxides and hydroxides, and molybdates, while importing 5394.9 tons of molybdenum ore and concentrates in the same year. Affected by the international market, China’s import and export of molybdenum ore-related products often change greatly every year. Table 3.14.15 reflects the import and export situation of molybdenum ore-related products in China in recent years.
