Nyrstar, the world’s largest producer of refined zinc, halted production at its Young mine in Tennessee after an equipment fire.
All employees have been evacuated, the company said in an e-mail today. Three miners who were trapped underground because of smoke were rescued at about 4 p.m. local time, it said. The mine employs 99 people, Renata Roberts, a spokeswoman said.
The company is working with the U.S. Mines Safety and Health Administration to ensure all areas of the mine are safe to resume operations, according to the statement.
Nyrstar bought the Young operation in December 2009. The company’s other five mines in Tennessee are continuing regular operations, Roberts said.
Nyrstar produced 63,000 tons of zinc in concentrate from its Tennessee mines in 2010, according to the company’s website.
