The XRT technology and larger screens will, as part of the new coarse recovery stream at the 150 tonne per hour diamond plant, provide capacity to recover individual diamonds up to 1,100 carats. The new XRT technology is also more effective for the recovery of higher quality low-luminescing Type IIa diamonds.
Lucapa Chief Executive Stephen Wetherall said the commissioning of the new XRT circuit represented another exciting new phase in the development of the Lulo diamond project. "We have seen what the implementation of this XRT technology delivered for Lucara - allowing their Karowe mine in Botswana to recover the second largest diamond ever," said Mr Wetherall.
"We are excited to have this XRT recovery technology now fully commissioned as part of our coarse material processing stream at Lulo, where we have already recovered five +100 carat diamonds this year."
"As well as treating the oversize or coarse gravels from daily mining operations, we will selectively process the 20,000 bcm of stockpiled oversize material over time."
