SÃO PAULO Bolivias Huanuni and Colquiri tin mines are expected to increase production in 2014 once Empresa Metalúrgica Vinto SA (EMV) starts up a new furnace, according to the countrys mining and metallurgy ministry.
The Ausmelt furnace, which is estimated to cost more than $33 million, was originally expected to begin operating in 2010 but successive delays pushed back the start.
State-owned EMV produces 12,000 tonnes of tin annually and aims to increase its output to 18,000 tonnes per year.
Huanunis output averages 800 tonnes per month, while Colquiri produces about 320 tonnes per month.
The Bolivian government nationalized Colquiri, which was operated by Glencore International Plc subsidiary Sinchi Wayra SA, in June 2012 (amm.com, June 21). Huanuni was nationalized in 2006.
