United Co. Rusal, the world’s largest aluminum producer, plans to increase output of high- purity aluminum used in computers and mobile phones as demand rises in Asia and the U.S.

Rusal’s Krasnoyarsk plant in Russia is targeting a 13 percent increase in output of the high-purity metal this year to 17,000 metric tons, the Moscow-based company said today in an e- mailed statement.

Rusal plans to restart 10 alumina-processing units that were halted two years ago as the global recession curbed demand. One of the 10 is already operational, it said.
