Zinc and lead prices maintained their strength throughout 2011 due to continued demand from China and India. Ore production from Tara Mines continued strongly throughout 2011. A brand new Autogenous Grinding mill, which replaces large sections of the original crushing and grinding plant, became operational in October 2009.

Zinc mining in the United States

When zinc demand increased during World War II, US smelters turned to foreign zinc ore. US-smelted zinc reached a high of 926,000 tonnes in 1970, then dropped as smelters closed. There were 12 primary zinc smelters in 1970, but only seven in 1980, three in 1990, and two in 2000.
