On June 1, a renowned industrial gas supplier, Praxair, revealed to a reporter that it has recently entered into a 15-year gas supply agreement with Jinlong Copper Co., Ltd., China's largest joint venture copper smelting company. Under the deal, Praxair will provide pipeline oxygen to Jinlong Copper’s production facility located in Tongling, Anhui Province.
To support Jinlong Copper’s fast-paced flash copper smelting process, Praxair will construct, manage, and operate three vacuum pressure swing adsorption (VPSA) oxygen generators with a combined capacity of 14,100 cubic meters per hour, equivalent to approximately 500 tons of oxygen daily. Construction of the oxygen plant has already commenced, with the first unit scheduled to begin supplying oxygen to Jinlong Copper in January 2007. The second unit is expected to go online in July of the same year, while the third will be commissioned by August 2008, marking the official launch of the entire plant.
In discussing the partnership, Jinlong Copper executives highlighted their commitment to continuously enhancing copper smelting technology. They emphasized the need for a reliable partner capable of delivering advanced gas supply solutions and ensuring consistent product quality. According to them, Praxair’s proven expertise and high-quality oxygen supply make it an ideal choice to meet their operational demands.
Praxair’s representative also expressed confidence in the collaboration, stating that the company’s extensive experience in metal smelting enables it to provide state-of-the-art gas supply systems tailored to Jinlong Copper’s flash copper smelting technology.
Jinlong Copper, a major joint venture, was established by Tongling Nonferrous Metals (Group) Corporation, Sumitomo Metal Mining Co., Ltd., Sumitomo Corporation, and Peace Fruit Aluminum Corporation. It specializes in producing high-purity cathode copper, along with by-products such as sulfuric acid, gold, and silver.
