General	The Teniente division, eighty kilometers South of Santiago and 2,500 meters above the sea level, its operations is the exploitation of the underground copper mine, which is the largest of its kind in the world. This mine, which began activities in 1904, has 2,400 kilometers of underground drifts. El Teniente produces 418,332 metric tons of fine copper per year as fire refined lingots (RAF), and copper cathodes. As a result of ore processing, 4,749 metric tons of Molybdenum were also obtained.

News	March 15, 1999 - Kvaerner, the Anglo-Norwegian engineering and construction Group, today announced that it has been awarded a contract to engineer, supply and construct a metallurgical sulphuric acid plant for Codelco, Division El Teniente, in Chile. Kvaerner Chemetics and Kvaerner E&C will provide basic and detailed engineering, procurement, construction services, and start-up assistance for the facility located at Codelcos Caletones Smelter, some 100 kilometres south east of Santiago. The site is one of the worlds largest underground copper mines. The new plant will reduce SO₂ emissions from the smelter and will complete Codelco's environmental upgrade to meet pending government regulations. The EPC turnkey project will produce a sulphuric acid plant to treat gases from the Teniente converter and two conventional converters at the Caletones Smelter. The plant will have the capacity to produce 2,350 tonnes of sulfuric acid daily. Kvaerner Chemetics in Vancouver and Kvaerner E&C in Santiago have begun design engineering work for the acid plant. The Kvaerner Chemetics portion comprises process engineering, mechanical design and equipment, and is valued at US$40 million, the balance being Kvaerner E&Cs detail engineering, construction, and bulk material supply. The twenty-two month project schedule calls for construction to begin in June 1999. The plant is expected to begin operation by January 2001.
