LONDON, Dec. 21 -- U.S. zinc producer Horsehead Corporation, a subsidiary of Horsehead Holding Corp. (ZINC), Tuesday said it has restarted a sixth zinc smelting furnace at its facility in Monaca, Pa., bringing the smelter back up to full production.
The company said it expects that by early January 2011 its oxide production capability will have returned to the rate it was before an explosion forced a shutdown in July.
Horsehead was forced to suspend its zinc oxide production process pending completion of an investigation after the incident, in which two workers were killed.
"Our progress in rebuilding the refinery remains on schedule," Chief Executive Jim Hensler said in a statement.
The zinc smelter and refinery plant in Monaca produced 106,000 metric tons of zinc in 2009.
