Canada-based Diamcor Mining has installed a deposit specific crushing circuit, along with Tomra XRT diamond recovery technology to process material in the +26.0mm size fractions at its Krone-Endora at Venetia project in South Africa.
With the installation of this equipment, the company aims to minimise the potential breakage of larger diamonds through a selective crushing system.
The company will also be able to operate independently from the current processing, using the new technology.
The Tomra XRT diamond recovery technology is a dry system. It requires no water and is expected to improve overall processing capacities.
Once the trial period is complete, Diamcor hopes to incorporate the technology into the projects’ facilities and operations.
Diamcor noted that majority of the rough diamonds recovered and sold to date at Krone-Endora have been a result of the processing of material in the +1.0mm to -26.0mm size fractions.
By deploying the new technology, Diamcor will be able to process material from the estimated +/-600,000t of +26.0mm material stockpiled at the project.
Diamcor signed an agreement to acquire the Krone-Endora at Venetia Project from De Beers in December 2008 and completed the acquisition in February 2011.
On 11 September 2014, the South African Department of Mineral Resources granted a mining rights for the Krone-Endora at Venetia project covering 657.71ha of the project’s total area of 5,888ha.
The Krone-Endora at Venetia project is located next to the De Beers Venetia diamond mine in the Limpopo province of the Republic of South Africa, about 500km north-north-east of Johannesburg.
