Antofagasta Minerals (AMSA) is one of the world’s largest copper producers. We are currently helping our customer to sustain its production level at the Los Pelambres mine in Chile, while reducing the environmental impact, establishing long-term relationships with neighboring communities, empowering local socioeconomic development and promoting the development of the local labor force.
Bechtel built the original copper concentrator at Chile's Los Pelambres Mine, located approximately 150 miles (240 kilometers) north of Santiago, between 1996 and 1999.
In 2001, we returned to add a $40 million pebble crusher. and followed that by installing additional conveying, grinding, and flotation equipment.
Bechtel's fourth Los Pelambres project, the Repower II expansion, increased the concentrator's capacity by 20 percent from 132,000 metric tons per day to 159,000 metric tons per day.
In early 2019, Bechtel began construction of the INCO MLP project at Los Pelambres.
