Cerro Verde II

The expansion of the world's largest copper concentrator plant was built in record time.



Proyect description:

CUMBRA built the plant in just 24 months – meeting the estimated deadline and budget for the work – dedicating more than 15 million hours of work and the participation of 2,600 employees at the peak of the work. In this way, our client tripled its production from 120,000 tons per day to 360,000 tons. This increases annual production to approximately 600 million pounds of copper and 15 million pounds of Molybdenum. Which makes this project one of the most emblematic in the region.
