Ausenco provided Engineering, Procurement and Construction Management (EPCM) services to design, construct, and commission a 25 mt/y concentrator and associated infrastructure for this high-altitude project.
Constancia is a conventional surface-mining operation based on two deposits - Pampacancha and Constancia - with the processing facility located around 1km west of the Constancia pit. The project incorporates primary crushing, twin SAG/Ball mill grinding circuit, regrind, flotation, concentrate filtration and tailings pumping capacity, as well as stand-alone molybdenum separation plant and various ancillary systems. The Pampacancha deposit is 5km southeast of the Constancia deposit and exhibits higher grades of copper and gold. It is scheduled to enter into production in 2016.
At full production, Constancia plant throughput will average 80,000 metric tons per day (mt/d), and production of copper in concentrate will average 82,000 mt/y. Mine life is planned at 22 years (view Hudbay video).
Ausenco's knowledge of Constancia was extensive having previously delivered to Hudbay:
Ausenco undertook project management and engineering which was distributed across Australia, Canada and Peru. Project management commenced in Brisbane and progressively transferred to Lima as the project developed.
Ausenco’s experience on the Constancia project married with proven execution strategies and a committed partnership approach resulted in the August 2015 announcement that Ausenco would provide EPCM services for the development of Hudbay Minerals' Rosemont Project near Tucson, Arizona, USA. The Rosemont Project, when producing, is expected to be one of the largest copper mines in the United States, accounting for around 10% of the nation’s copper production.
10 years on, Greg Lane reflects on the design and construction of the then largest copper concentrator in Africa.Read Article
