Compania Minera El Indio Gold, Silver, and Copper Processing Facilities

Fluor provided engineering, procurement, construction management, and start-up services to Compañía Minera El Indio for gold, silver, and copper processing facilities at a site 14,000 feet up in the Chilean Andes.

Fluor implemented innovative techniques to complete this project in the remote mountains of Chile.

Due to the constant cold, concrete was heated for proper curing. Grout was used to seal large pipe covered with tents to prevent the dry winds from evaporating moisture from the mixture. Fluor also used pack mules to carry material to transmission tower sites located in isolated areas.

Despite the challenging conditions, the Fluor team successfully completed the copper, silver, and gold mine project with an experienced site team and dedicated Chilean construction crews.


Mining Processing Facilities Construction Site
Client's Challenge

Compañía Minera El Indio wanted to build mine-processing facilities in an isolated location 14,000 feet up in the Chilean Andes. The project site's severe climatic conditions presented several challenges, including lack of infrastructure and the logistics of getting equipment and workers to the site.

The facilities would process 437,500 metric TPY of copper-, gold-, and silver-bearing ore and would include installation of roasting facilities to upgrade the concentrates and carbon-in-pulp / electrowinning capabilities for gold and silver bullion recovery.
