The smelter is on schedule to partially begin operations with gas on June 1, 2003, and the whole plant should be running on that fuel by the end of 2004, El Teniente spokesperson Rodrigo Rivas told Reuters.The project is part of El Teniente's environmental clean-up and cost-reduction plan. Natural gas will reduce sulfuric emissions at the smelter and also cut down on operating costs, Rivas said.
El Teniente produced 350,000 tonnes copper last year.
GasValpo, owned by the Australian Gas Light Co , signed a contract with El Teniente last December to supply the gas for 15 years.
The gas comes from Argentina's Neuquen province and is transported via pipeline to central Chile by GasAndes.
The construction of gas distribution networks at the plant site is scheduled to commence in November and to be completed in May 2003.
The plan also includes the construction of two plants to convert sulfur emissions into sulfuric acid, which will be operational from 2003 and be capable of trapping 92 percent of sulfur emissions.
El Teniente is one of five mines wholly-owned by Codelco. The state miner also has a 49 percent stake in El Abra, controlled by Phelps Dodge .
