Updated 1:20 p.m. August 1 with reopening of smelter

The Doe Run Peru smelter in La Oroya, which had been clsoed due to financial and environmental compliance issues since 2009, resumed zinc processing operations over the weekend.

Peru's Minister of Energy and Mines, Jorge Merino Tafur, is reported to have said that lead smelting would also resume in the not too distant future. Restarting copper production would likely take longer, since that would require building a plant to control sulfuric acid emissions.
