Increasing daily throughput

The Minera Esperanza mine in Chile has decided to commence a project with Metso which targets to increase the mine’s annual production of copper and gold by 15-20 %. This will be done by installing a 20 000 t/d crushing and screening system which bypasses part of the mine’s existing grinding circuit. The new plant is scheduled to start operations in 2015. There will be a site team of over 500 people during the peak phase of the project. The order, worth of around 80 million €, was booked in Mining and Construction’s Q4 2013 orders received.

Included in the project will be equipment for materials handling, crushing and classification, as well as engineering, automation and electrification, structural steel, civil works and electromechancal installations required for the new plant. The equipment to be supplied for the new crushing plant consists of three MP 1000 cone crushers, three multi-flo double deck banana screens in two sizes, seven belt feeders, two pan feeders and nine belt conveyors with a total length of 1 km.
