10 years on, Ausenco reflects on the design and construction of the then largest copper concentrator in Africa.
Located in the North Western Province of Zambia, the Lumwana Copper Concentrate Project is one of the largest copper projects in Africa processing 20 million tonnes a year over a 37 year life-of-mine.
Ausenco’s scope included the design, supply, construction and commissioning of a 20 Mt/y copper concentrator including associated on-site infrastructure. With extensive experience delivering low cost plants, Ausenco designed a capital efficient concentrator without compromising our core values of safety, and operability.
Ausenco identified numerous capital reduction strategies, including:
The project was completed within budget and with over 5 million man hours LTI free out of a total of 7.8 million man hours worked. Logistics and freight were executed without delay and new procurement networks were successfully established in southern Africa. At peak construction, 2,300 personnel were employed, with 90% of the work force local.
The above lump sum EPC project was completed in 2008. In 2010, Ausenco optimised the process plant to 25 Mt/y and provided EPCM services for another 25 Mt/y crushing circuit and infrastructure for a new open pit at the project.
