Expanding the world's largest open-pit copper mine
Bechtel provided engineering, procurement, and construction services for the expansion of the world’s largest open-pit copper mine, Minera Escondida Ltda. We completed the billion-dollar job in 2002. Our scope of work included building a new copper concentrator, upgrading crushing and material-handling systems, and constructing a 6.2-mile- (10-kilometer-) long conveyer system.
The project was a joint venture of Bechtel and Sigdo Koppers, the same team that successfully completed the Phase 3.5 expansion of the mine in 1998.
