Diamond miner Lucara Diamond will be installing additional XRT diamond sorters, worth $30 million, to process finer diamond size fractions at its Karowe mine in Botswana.Lucara Diamond says the project, through the installation of four new XRT diamond recovery units and the associated conveying and screening infrastructure, will target the recovery of diamonds in the size range of between 4 mm and 8 mm.
The XRT technology, which is already in use at the Karowe mine will address processing of the very dense high quality south lobe ore at depth. This will result in the most efficient and cost effective processing methodology for processing this ore.
The project is expected to be completed in the fourth quarter of 2017.
Lucara Diamond continues to lead the way in the adoption of new technology to streamline the diamond recovery process with the XRT technology being a proven success for diamond recovery at the company's Karowe mine," says president and CEO William Lamb.
“The extension of XRT technology to recover the majority of our diamonds at Karowe maximises our overall processing efficiency and will contribute to continued strong operating margins across the entire value range for our high quality south lobe diamonds,” he says.
In addition, the implementation of the new diamond sorters will allow for improved control of the size fractions treated by the XRT machines allowing for improved flexibility and an expected improvement in production rates.
