New Technology for a ‘new’ Mine

A sustainable, innovative partnership for reactivating a Philippine Copper Mine
In 2007 a Philippine copper mine was reactivated after half a decade of decommissioning. To improve the technical and financial results the mining company engaged a specialist company for the upgrade and expansion of the concentrator plant, the capacity of which grew by 50 %.

State-of-the-art Technology

Designed to cope with projected increases in throughput and recovery, Outotec’s new concentrator technologies at site comprise comminution, flotation, thickening, analyser and DCS systems. Considerably more operator friendly, the upgraded circuit offers easier and safer access. The new system delivers advanced analysis and automation for up-to-the-minute process stability, and is aimed at providing maximum availability and optimised recovery. Commissioning of the upgrade was due to commence in the fourth quarter of 2013.

Future Development

The Carmen Copper expansion project has afforded Outotec a unique opportunity to work closely on a significant brownfield concentrator expansion project. This project required very close on-site liaison with the client, who has been responsible for construction. Through collaboration, Filipino subcontractors and partners were utilised for detailed engineering and the Carmen Copper project as a whole has facilitated development of concentrator engineering, procurement and project management. With forward planning, Carmen Copper has the flexibility to undertake further expansions in the future.
