Escondida has a treatmen capacity of 230,000 tpd in its two concentrator plants
This is conducted in two concentrator plants: Los Colorados, with a processing capacity of 120,000 tpd and the Laguna Seca plant, with a processing capacity of 110,000 tpd.
The copper concentrate produced by both plants is sent through two slurry pipelines, to the Coloso Port facilities located south of the city of Antofagasta. At Coloso, the pulp undergoes a pressure filtering process after which concentrate is obtained with 9% humidity. The concentrate is later shipped by land to consumers in Chile and by ocean freight to the various clients around the world.
