Elizabeth Bay diamond-treatment plant upgrade



At the signing of the Elizabeth Bay upgrade contract was (l to r) BATEMAN Project Manager, Francois Roos; Namdeb Regional Project Manager, Byron Higgins; BATEMAN Senior Manager, Strategic Development, Rob Bennett; Namdeb Managing Director, Ms Inge Zaamwani; Namdeb General Manager, Rob Smart and Namdeb Project Manager, Ian Holl.


BATEMAN has been awarded a contract to upgrade the treatment plant at Namdeb’s Elizabeth Bay Mine near Lüderitz on the coast of Namibia. The contract forms part of the Elizabeth Bay Liberation Project and was formally signed in Lüderitz, Namibia on 10 April 2003.

The N$400M project, which commenced in November 2002 and is scheduled for completion in June 2004, involves both modification and technological upgrade of the existing treatment plant, thus making it possible to treat much of the mine’s remaining potentially-viable deposit.

The project has the potential to increase the life-of-mine by at least 10 years and will enhance the sustainability of Lüderitz. It will provide ongoing employment for the existing staff of about 170, as well as creating close to 40 new permanent jobs. During project execution, it is planned to employ Lüderitz residents as more than 80 % of the 500 project personnel during the peak of the construction phase, with a small percentage of technical staff being drawn from South Africa.

The comminution technology included in the flowsheet design makes it possible to handle previously-untreatable cemented ore, clay-rich ore and wet material. The existing process was designed to treat exclusively dry run-of-mine feed.

BATEMAN will engineer, design, procure and construct the extension to the current plant which includes primary, secondary and tertiary crushing, two stages of primary screening and a ball-milling process.

BATEMAN Senior Manager, Strategic Development, Rob Bennett, said a special feature of this project is that it represents a true partnership between the parties involved, BATEMAN and Namdeb, to maximise the synergy between the respective organisations’ core capabilities.

“BATEMAN contributes specific diamond process and flowsheet integration skills, experience in project execution in Namibia, as well as proven project-management systems and implementation capability; and Namdeb, detailed knowledge of the resource and operations in the area, access to the De Beers group technical- and operational-expertise base and an ongoing commitment to the local Lüderitz community.

“The project’s contract deviates from the typical contractor / client arms-length agreement in many respects and provides a solid platform for meaningful collaboration between the parties at all levels, both internally and external to the core project team, all aimed at bringing the project in on time and on budget. In return, any savings and benefits gained are to be shared equally by the partnership,” says Bennett.

“Furthermore, an important feature of this contract is that the success will be measured not only in traditional terms of time, scope and budget, but also in terms of the long-term positive contribution to the local Namibian community.” For more information, please contact:
