Minera Escondida Limitada is the largest single mine copper producer in the world. In the year 2006, production reached a record of 1,255,599 metric tons of fine copper, representing approximately 8.1% of world copper production and 23.4% of Chilean production.
Minera’s Escondida deposit, which was initiated in August of 1988, is located in the North of Chile, in the Atacama Desert, 170 km southeast of the city of Antofagasta, at an altitude of 3,100 meters above sea level. Productive operations began in 1990, and since October 2005, the company also operates Escondida Norte, which is a second open pit located 5 km from the main pit.
Minera Escondida produces copper concentrate by means of the sulphide ore flotation process, and also produces copper cathodes using the oxide ore leaching and low-grade sulphide bio-leaching processes. The company moves around 360 million tonnes of mineral annually.
Minera’s infrastructure consists of two open pit mines (Escondida and Escondida Norte), two concentrator plants (Laguna Seca and Los Colorados), an electro-winning plant to produce cathodes from oxide and sulphide ore, and two pipelines that transport copper concentrate from the mine to the filter plant, which is also owned by the company and is located at the Port of Coloso, in the far south area of the city of Antofagasta. A seawater desalinization plant was recently built in that same area to supply part of the operation’s water consumption.
The development, start-up, and subsequent expansion phases of the company (which have increased production capacity from 320,000 to more than 1,200,000 metric tons of fine copper annually) have not only been the natural result of having an enormous and rich field and applying modern technologies, but also mainly due to the technical capacity and vision of its people, who have developed this mega operation with special care being given to the various sustainability aspects of the business.
Minera Escondida aspires to be the world’s leading copper mine, creating value in a sustainable manner through superior performance in the industry in terms of safety, production and unit costs. The purpose of the company is to create value for its shareholders, employees, communities, clients and suppliers, through low-cost production of high quality cathodes and copper concentrate. Guided by the Charter, a document that was adopted from the BHP Billiton Charter in the year 2002 (BHP Billiton is the principal owner and operator), the company works to achieve excellence in safety and production as well as in its respect and care of the environment and commitment to the community.
