Expanding the World’s Largest Copper Mine

The Escondida mine is located 105 miles (160 kilometers) southeast of Antofagasta in northern Chile and represented 9 percent of the global copper market at the time of the project. Aiming to increase ore processing capacity, our customer developed the Escondida Phase IV project.  

Escondida Phase IV Workers

8868体育app下载 provided engineering, procurement, and construction services for the expansion of the world鈥檚 largest copper mine, , completing the billion-dollar job in 2002. Our scope of work included building a new concentrator, upgrading crushing and material-handling systems, and constructing a 6.2-mile鈥�(10-kilometer) long conveyor system.鈥� 

The project was executed by a joint venture between 8868体育app下载 and Sigdo Koppers (now known as Ingenier铆a y Construcci贸n Sigdo Koppers), the same team that successfully completed the mine鈥檚 Phase 3.5 expansion in 1998.
