KGHM International Ltd. Sierra Gorda Copper-Molybdenum Mine Project

Fluor was awarded a contract in 2011 to perform engineering, procurement, and construction management services for the Sierra Gorda Mine processing plant.

The processing plant consists of: primary, secondary, and tertiary crushing with high-pressure grinding rolls (HPGRs); ball milling and conventional flotation to produce a bulk copper-molybdenum concentrate; train transport of bulk copper concentrate to the Port of Mejillones for loading into ships; and train transport of bagged molybdenum concentrate to the port for further transport to a toll roasting facility or end user.

Fluor conducted a feasibility study for KGHM International Ltd. open pit operation prior to the award. The feasibility study focused on the principal sulfide ore, which is processed at an initial daily throughput of 110,000 tons per day (tpd) with provision for potential expansion to 190,000 tpd.

The project facilities included those for open pit mine development and preproduction stripping. The mine is 1,700 meters above sea level.
