China Minmetals Nonferrous Metals, the mainland's largest importer of alumina and a subsidiary of Minmetals Group, aims to raise one billion yuan in a Shanghai listing this month or early next year. Vice-president Wang Lixin said the firm had applied to the China Securities Regulatory Commission for the listing, and preparatory work had largely been completed. 'Timing of the listing will depend on when the regulators give us the green light,' Mr Wang said on the sidelines of an aluminium industry conference in Beijing yesterday. He said China Minmetals had no plan to list overseas but had the option to do so. Mr Wang also said China Minmetals was one of the bidders of assets being sold by North America's third-largest producer, Kaiser Aluminium, in its bid to emerge from bankruptcy protection. They include interests in two alumina refineries - a bauxite mine in Jamaica and an aluminium smelter in Wales. The tendering process is expected to be completed by March or April next year. China Minmetals entered into a 30-year contract to buy 400,000 tonnes of alumina annually from the world's biggest producer, Alcoa. In March last year, it formed China United Copper with five of China's largest smelters, including H share Jiangxi Copper, to strengthen their bargaining power for copper concentrate imports.
