DCD-Dorbyl Heavy Engineering has been commissioned by various divisions of Outotec – a leading global provider of process solutions, technologies and services for the mining and metallurgical industries – to produce no fewer than 19 ball and SAG mill shells for customers in three African and six overseas countries. This is a set of orders which will take the company well into 2008, according to marketing manager Bennie Bosch.
According to the judges, the plants – which were installed and commissioned at Snap Lake, near the Arctic Circle, and Victor, in Canada – demonstrated De Beers’ ability to accomplish a uniquely challenging task in the most arduous physical conditions.
“It is hard to imagine a more inhospitable site to build a plant than one close to the Arctic Circle, where temperatures are known to plummet to minus 50 degrees,” the judges pointed out. “Not only was special steel suitable for such conditions required, but working conditions were gruelling and the logistics proved to be a nightmare,” they added.
It is the Lerala diamond mine, situated in eastern Botswana some 80 km south of Selebi Phikwe, and developed by Brisbane-based specialist diamond explorer DiamonEx Limited, which is listed on both the Australian and Botswana stock exchanges.
“After completing our feasibility study and applying for and obtaining our mining lease, we started construction less than a year ago, and our first production will be happening in the new year,” says managing director Dan O’Neill. ‘‘We will ramp up to full production by the end of Q1 in 2008,” he adds.
“This has been achieved,” says managing director James Campbell in an exclusive interview with Mining Review Africa, “by acquiring a 35.42% share in Bugeco SA – a private Belgian company cooperating in the DRC. The total consideration paid was just over US$1.6 million (more than R11 million) in cash.
Bugeco’s key asset is a joint venture with De Beers on 22 licences covering 17 480 km2 of prospective diamondiferous ground. Initial exploration has discovered several new kimberlites in an area where alluvial diamonds are already in evidence. Analysis indicates the presence of microdiamonds in several of the newly discovered kimberlites.
Canadian-listed diamond mining company Rockwell Diamonds Inc. has signed a major new deal with Cape Town-based security solutions company i to i technologies to establish the world’s first turnkey security initiative for its South African mining operations.
Roll-out of the state-of-the-art system is underway, with teams actively working at Rockwell’s Northern Cape mines, which include the Holpan Klipdam property, located 45 km from Kimberley.
A new product with certain applications in the mining, quarrying and construction industries has been launched on the South African market. The manufacturers claim that it can crack even the largest rocks overnight, with no flying debris and no danger to the surrounding environment.
One of the leading mining engineering consultancies in South Africa, Read, Swatman & Voigt (Pty) Ltd (RSV), is expanding its client base to include investors and lenders in the mining industry to meet the increasing demand for high-level evaluations of mining projects. These include initial technical assessments, due diligence studies, competent person’s reports and feasibility studies.
In a move to enhance its technology offering in the field of minerals processing, Johannesburg– based IMS Engineering has entered into a partnership with Colognebased Steinert Elektromagnetbau GmbH – a global leader in separation technology for the recycling, metals and mining industries.
This partnership enables the South African company not only to offer the sensor-based separation and sorting systems it has become known for – like optical and X-ray sorting – but also the more traditional Steinert separation systems that use eddy current and magnetic technologies.
