Trace Depth of Nickel in China
There are more than 10 nickel mines now under operation in China, of which the main ones are the Jinchuan nickel mine in Gansu, the Hongqiling nickel mine in Jilin, and several other mines under the Jilin Nickel Co. The Jinchuan nickel mine alone produced 1.65 million tons of ores in 1994, which accounted for 82.5% of the country’s total (Table 3.10.3), and its electrolytic nickel production in the same year made up 78.7% of the country’s total nickel output. In addition, the Kalatongke Cu-Ni mine in Xinjiang has a mining capacity of 75,000 tons per year and the Baimazhai Cu-Ni mine in Yunnan, 15,000 tons per year.
The Jinchuan Nonferrous Metals Co. is the largest nickel producer in China. The commencement of operation of the Jinchuan mine in the 1960s caused a great change in the nickel production of the country. Its first-phase project, after being constructed, provided an annual productive capacity of 20,000 tons of electrolytic nickel; the second-phase project for expansion was completed during the 8th Five Year Plan, which would double the annual productive capacity of electrolytic nickel to 40,000 tons. In 1995, the company produced 33,024 tons of nickel, 14,725 tons of copper, 390 tons of cobalt, 528 kg of precious metals and 100,500 tons of sulfuric acid.
The Jilin Nickel Co. is located at the Hongqiling Town, Panshi County, Jilin Province. Its mines were constructed in 1960, forming the second largest nickel production base in China. Its productive capacity includes the following: the Fujia mine has a designed capacity of underground mining and supply of 600 t/d; the Daling mine can tackle underground mining and supply of 400 t/d; and the Piaohe open-pit mine can exploit 200 t/d, dress 1,500 t/d, and smelt 2,625 t/d of nickel matte. In 1995, the company actually produced 4,567 tons (nickel content) of nickel matte, 1,100 tons of nickel sulphate, 760 tons (copper content) of copper concentrates, and 12,800 tons of sulfuric acid.
The Huili nickel mine was designed and constructed in 1958 on the basis of the Limahe Cu-Ni deposit in Sichuan. In 1966, the mine was capable of mining and dressing 500 t/d and roughly smelting 1,200 t/a (nickel content). In 1983, the main orebody at the pithead of the Limahe mine was mined out. In 1986~1992, a mine capable of mining and dressing 100 t/d was gradually constructed at Lengshuiqing, Yanbian, Sichuan. In 1995, the mine was expanded and renovated, obtaining a mining-dressing capacity of 300 t/d. The ore dressing project was entirely completed at the end of the same year and the whole expansion-renovation project was accomplished in 1996. Despite of the construction, the mine produced 1,053.7 tons (nickel content) of nickel matte in 1995.As the professional manufacturer of complete sets of mining machinery, such as stone crusher,dryer machine, Henan Hongxing is always doing the best in products and service.
The Xinjiang Nonferrous Copper-Nickel Co. (the former Koktokay Mining Bureau of Xinjiang), located in Fukang City and founded in 1950, is a large complex of nonferrous metals capable of ore mining, dressing and smelting and owning the Koktokay rare metal mine, the Kalatongke Cu-Ni mine and the Fukang Smelter. In 1984, the company worked out the policy of ¡°promoting the rare metals industry and energetically developing the nonferrous metals industry’ for the growth of the enterprise; and constructed an electrolytic aluminum plant annually producing 2,400 tons of aluminum ingots, the Kalatongke Cu-Ni mine capable of producing 3,500 tons of nickel matte per year, and the Fukang nonferrous metals metallurgical base that is dominated by copper and nickel smelting and can annually produce 2,040 tons of electrolytic nickel.

The Sichuan Copper-Nickel Co. Ltd., formed by restructuring of both the Chengdu Electric Smelter and the Lala copper mine, is a company solely funded by the State and engaged rnainly in mining, smelting and processing of nonferrous ores. It now has the productive capacity of daily mining and dressing 1,500 tons of copper ores and yearly producing 5,000 tons of electrolytic nickel, 5,000 tons of electrolytic copper, 60 tons of electrolytic cobalt and 100 tons of sulfur-bearing active nickel.
Besides the above-mentioned large nickel producers, some smelters in Chongqing (of Sichuan). Zhejiang and Henan are producing nickel.
Nickel smelting is conducted mainly by the Jinchuan Nonferrous Metals Co. in Gansu the Koktokay Mining Bureau in Xinjiang the Jilin Nickel Co.£»the Huili nickel mine, Chengqing Smelter and Chengdu Electric Smelter in Sichuan the Yiwu Smelter in Zhejiang and the Xinyang Smelter in Henan.
