(1) Jiangxi Copper Base Jiangxi Copper Mine is rich in resources and ranks first in the country. The proven copper industry reserves (A + B + C reserves, the same below) account for 1/3 of the country's copper industry reserves, and it is the largest base for copper production in China. In 1978, the country listed the Jiangxi Copper Base as a national key construction project. Jiangxi Copper Company was established in 1979 and currently owns two factories, namely the Dexing Copper Mine, Yongping Copper Mine, Wushan Copper Mine, Dongxiang Copper Mine, Chengmenshan Copper Mine (to be built), Yinshan Lead and Zinc Copper mine and Guixi smelter, Shanghai smelter. The six large and medium-sized mines have proven copper reserves totaling 13.87 million tons, of which the Dexing Copper Mine is an ultra-large copper (molybdenum) ore field. The Dexing Copper Mine formed a scale of 100,000 t/d in 1993 and became Asia. One of the very large mines. The five mines currently mined are producing 102,000 tons (1996) of copper concentrate (metal content, the same below), accounting for 1/3 of CNNC's copper concentrate output and accounting for 1/4 of the country's total copper concentrate output. Jiangxi Copper Company produced 206,600 tons of copper in 1996 (including 165,500 tons of Guixi smeltery), accounting for 1/3 of CNNC's copper production, accounting for 1/5 of the country's total copper output.
(2) Yunnan Copper Base The Yunnan Copper Mine is rich in resources, and the proven reserves of copper industry ranks second in the country. The base is composed of "Four Mines and One Plant", namely Dongchuan, Yimen, Dayao, Luding and other four large and medium-sized mines and the Yunnan government refinery. The Yunnan Copper Industry (Group) Co., Ltd. currently established has an annual output of 100,000 tons of copper and 50,000 tons of copper concentrate in 1996. It is the second largest copper production base in China.
(3) Baiyin Copper Base The Gansu Baiyinchang area is one of the copper enrichment areas in China. It consists of folding waist mountain, flaming mountain, Tongchanggou, Xiaotieshan, and four circle deposits. Established Baiyin Nonferrous Metals Co., Ltd. for the development of Baiyinchang Copper Mine Resources and listed mine mining and dressing and metallurgy as one of the country's first five-year plans for key construction projects, unveiling the construction of large-scale copper enterprises in the 1950s. prelude. After three years of large-scale construction from 1957 to 1959, two open-pit mines and ore-dressing factories and smelters at Zheyao Mountain and Huoyan Mountain were built with high speed and high quality. The original design capacity of 30,000 tons of copper per year, after the technical transformation of 50,000 tons, once the country's largest copper production of large-scale mining, mining and smelting joint venture. In 1996, it produced 60,000 tons of copper.
(4) Northeast Copper Base The base is composed of a group of small and medium sized mines, with early start and rapid construction. From 1948 to 1950, Liaoning Qingyuan Copper (Gold) Mine, Huatong Copper Mine, Furong Copper Mine, Malugou Copper Mine, Jilin Shizuzi Copper Mine and Tianbaoshan Copper Lead-zinc Mine resumed production, and the Shenyang Smeltery also The production was resumed in January 1949. Since then, China's first copper mining and metallurgical production base has emerged in the northeastern region, laying the foundation for the development of China's copper industry and playing a leading role. In the 1950s and 1960s, a large number of management talents and scientific and technological backbones were transported to non-ferrous metals enterprises throughout the country, which strongly supported the development of the national copper industry. In the 1960s, the mining resources mentioned above were successively closed and pits were closed. The mines of Huanren and Hongtongshan took over and purchased mineral raw materials, which enabled the continuous production of the Northeast Copper Base and produced 50,000 tons of copper concentrate. The annual output of copper in 1996 was 7 Million t. In particular, there is still a large-scale porphyry copper deposit in Heilongjiang, which is yet to be developed. It can be used as a raw material supply base for Shenye minerals. Therefore, the northeastern copper base still has stagnant production.
(5) Tongling Copper Base Anhui Tongling is located in the middle and lower reaches of the Yangtze River. The construction conditions are good and the resources are abundant. The copper reserves of a group of large and medium-sized deposits, such as Tongguanshan, Shizishan, Da Tuanshan, Dongguashan, Fenghuangshan, Xinqiao, Guichi, Anqing, Lushan, Shaxi, etc., have been proven to have copper reserves of more than 3 million tons. The base is also a base for early construction and quick start. It is the first base to produce 10,000 tons of copper per year during the "1st Five-Year Plan." The Tongling Nonferrous Metals Company now owns six mines and two smelters. In 1996, it produced 42,000 tons of copper concentrates and 46,500 tons of copper, which is a large-scale mining, mining, and processing joint venture.
(6) Daye Copper Base The copper resources of Hubei Daye, Huangshi and Yangxin areas are rich in resources, and the proven copper reserves total more than 3.6 million tons. Daye Non-Ferrous Metals now owns the “Two Mines and Two Plantsâ€, which are copper and copper smelters and a copper smelter in Tongkushan, Fengshan Cave, Tongshankou, Chimashan, Daye Copper Plant, Xinye, etc. Material processing factory. In 1996, it produced nearly 20,000 tons of copper concentrates, 61,600 tons of crude copper, and 45,600 tons of copper. It is a large-scale mining, mining, and processing joint venture.
(7) Zhongtiaoshan Copper Base Shanxi Zhongtiaoshan Area Since the 1950s, large- and medium-sized copper deposits such as copper ore, Xiaoxigou, Hujiayu, Yanzigou, and Luojiahe have been explored, and cumulative copper reserves have been more than 3.3 million tons. . In order to develop copper resources in this area, Zhongtiaoshan Nonferrous Metals Co., Ltd. was established in 1956. Now it owns “Three Mines and Two Plantsâ€, namely large- and medium-sized copper mines such as copper ore mines, Hujiabang and Yanzigou, as well as a smelter and an electrolytic copper plant, forming a large-scale joint venture with mining, mining, and metallurgy as the main body. In 1996, it produced 27,200 tons of copper concentrates, 26,000 tons of crude copper and 11,600 tons of copper.
Since the 1950s, China has established seven large-scale mining, metallurgical and metallurgical joint ventures based on the Seven Copper Bases, 14 large- and medium-sized crude copper smelters, and 67 electrolytic copper plants. See Table 3.7.12 for the overview of major enterprises.
China's copper production layout
According to the geological prospecting available copper resources and the distribution and construction conditions of the deposits, more than 100 state-owned copper mines have been built. Among them, China Nonferrous Metals Industry Corporation (CNNC, hereinafter referred to as CNNC, the same below) is directly subordinate to 37 mines, and now has formed a seven-copper production base with mining as its main body.
