General Yunnan Copper Corporation (YCC), a company based in Kunming, Yunnan Province, China, commissioned their copper ISASMELT plant in May 2002. YCC were extremely impressed with the advantages offered by the ISASMELT technology, including its low energy consumption, small physical footprint, its ease of operation and the improvements it would make to environmental performance for the plant.

The ISASMELT furnace can treat up to 800,000 tpa of copper concentrate. The furnace produces a copper matte with a copper content of 60%. Process air is enriched to 50% oxygen content. The ISASMELT furnace installation has significantly improved the environmental performance of the smelter and has resulted in a significant reduction in operating costs.

Yunnan Copper Co., Ltd. is one of the "super-size" state owned copper operations in China, with total assets over 8.5 billion RMB Yuan. The annual revenue in 2001 was 4 billion RMB Yuan. Guaranteed geologic reserves of copper metals exceed some three million tons. Yunnan Copper Co., is a copper complex with diversified industries such as mining, smelting, research, and trading. Its main products include copper concentrates, blister copper, copper cathodes, copper core, gold, silver, sulfuric acid, cupric sulfate, nickel sulfuric, electrolytic aluminum, electrolytic zinc, metal high abrasive materials, etc.

China United Copper Co., Ltd. (CUC) www.cucltd.com

China United Copper Co., Ltd. (CUC) was established on 15 March, 2002 in Beijing, China. CUC is a jointly owned company, and was co-founded by China Minmetals Non-ferrous Co., Ltd. and the five backbone smelters in China: Jiangxi Copper Co., Tongling Non-ferrous Metals (Group) Co., Ltd., Yunnan Copper (Group), Ltd., Daye Non-ferrous Metals Co., Ltd., and Shanxi Zhongtiaoshan Non-ferrous Metals (Group) Co., Ltd. The registered capital is 10 million RMB Yuan.
This is the first time for the Chinese copper industry to organize the six industry-giants into an alliance to deal with non-domestic entities and projects. It marks a new milestone for China's copper industry.
CUC's aim is to unify Chinese copper smelters from separate business units into a strong business alliance for the negotiation and import of copper concentrate. Such a strategic action ensures the partners' common interests, namely creating a harmonized "voice" in negotiations with foreign mine-owners concerning joint exploitation and development of overseas mines. The result is the strategic stabilization of raw material supplies for China's domestic smelters, by obtaining the long-term overseas sources. This is a historical moment for our cooper industry, a turning point from short-term and spot copper purchases toward mid-term/long-term and strategic purchases. In addition, the joint development of new overseas copper mine resources will lead toward the realization of long term security.

News March 31, 2011 - Yunnan Copper posted a 15.61 percent year-on-year increase in 2010 net profit attributable to shareholders to 431 million yuan on a 95.95 percent increase in revenue to 31.71 billion yuan, reports 163.com. Earnings per share was 0.34 yuan. The refined copper production volume totaled 326,400 tons in 2010. Gross margin was down by about 70 percent due to the shut down of its furnace for maintenance.  The gross margin of its sulfuric acid business surged 1.5-fold due to higher market prices.  The company aims to produce 351,000 tons of high-purity copper cathode, 54,300 tons of copper concentrate, 901,400 tons of sulfuric acid, 6.35 tons of gold, 271 tons of silver and 651,500 tons of iron concentrate in 2011.

April 19, 2010 - Yunnan Copper Co., the third-largest copper producer in China, last week said that it expects to be back in the black in the first quarter of this year due to a substantial increase in sales volume and revenue, sources reported.  In a statement filed with the Shenzhen Stock Market, Yunnan Copper said that its net profit in the period from January to March may be between RMB 160 million and RMB 190 million with earnings per share of RMB 0.13 to RMB 0.15.  The company posted a net loss of RMB 261 million for the first quarter of last year.  Early this month, the firm, which is principally engaged in the production and sale of copper concentrates and precious metals, posted an RMB 373-million net profit for last year, whereas it suffered RMB 2.8 billion in losses in 2008. Earnings per share were RMB 0.3, and no dividend was declared.  In 2009, Yunnan Copper produced 286,700 tons of refined copper, 724,600 tons of sulfuric acid, 8.1 tons of gold and 310 tons of silver, according to the firm's annual report.

January 3, 2010 - China largest and third largest copper producers Jiangxi Copper Corporation and Yunnan Copper Company Limited respectively have become partners with China Minmetals Group and Aluminum Corporation of China Limited and now Tongling Nonferrous Metals which is the second largest copper producer has finally found someone to fall back on.  Tongling Nonferrous announced December 29th 2009 that its majority shareholder Tongling Nonferrous Metals Group Holdings Company Limited have joined China Railway Construction Corporation and acquired 66.67% of the shares of Canada's Corriente Resources with CNY 4.41 billion.
Tongling Nonferrous Metals Group defeated many competitors for the acquisition. According to Reuters news agency last year, companies including Tongling Nonferrous Metals Group, the world's fourth largest copper producer Switzerland's Xstratar Company and the world's largest copper miner Chile's state copper company Codelco all expressed interest in participating in Corriente Resources' Panantza, San Carlos project in southern Ecuador.
Compared with domestic counterparts, the acquisition mode is very similar to an overseas acquisition case by China Minmetals Group and Jiangxi Copper 2 years ago. Tongling Nonferrous Metals Group first set up a joint venture company with China Railway Construction Investment Company Limited and then acquired Corriente Resources through this JV.
Although Corriente Resources is listed on the Toronto Stock Exchange and the New York Stock Exchange at the same time, its main asset lies in mineral assets and mineral interest in the Corriente Copper Belt in southeastern Ecuador.
Now these 3 companies have found partners, the current pattern of competition in the domestic copper industry has also changed. China Railway Construction which had never been in the mining industry said its Board of Directors meeting held October 27th 2009 has decided to make mineral resources development one of the company's main businesses. This adds another central enterprise in the mining industry.
