ノリリスク・ニッケル
More than 51% of Russia's copper metal production was produced by Norilsk Nickel from ore mined by the company. The remainder came from a much smaller amount of ore mined in the Ural Mountains and a large amount of secondary material. As nickel-rich ores at Norilsk Nickel become depleted, Norilsk Nickel will switch to mining larger quantities of ores, which will be primarily copper-rich ores that have a higher copper content relative to their nickel content than the nickel-rich ores, but are lower in metal content for both metals. This change could increase copper output as Norilsk Nickel tries to maintain its level of nickel production. Norilsk Nickel's strategy up to 2010, however, appears to be to maintain its production of nickel-rich ores which may delay the significant increase in copper production.
