Global Mining Review,

The priority at the top of the list of every diamond producer is to maximise diamond recovery, whilst optimising costs as well as acting on the growing pressure to address corporate social responsibility and environmental issues. TOMRA is receiving increasing enquiries from existing and new customers, looking to update their plant or complete the process with the company’s revolutionary Final Recovery sorter.

Live demonstrations reveal the full potential of TOMRA’s Final Recovery sorter

A key element of TOMRA’s full solution is the COM XRT 300 /FR Final Recovery sorter, which the company has been demonstrating at its Demo Rooms in Wedel, Germany, and Johannesburg, South Africa. These demonstration facilities are proving particularly valuable for diamond operators, who have the opportunity to experience first-hand the unique benefits of this revolutionary and easy-to-operate compact final recovery sorter. They can watch accurate demonstrations of typical final recovery, sort house and single particle sorting functions, across various size fractions with either kimberlite or alluvial ore, and experience sorter outputs at various feed rates exhibiting actual on-mine conditions. The TOMRA operator can show them how their unique operational requirements would be addressed on a live easy-to-use human machine interface (HMI) panel.

Corné de Jager, Diamond Segment Manager TOMRA Mining, comments:

“The biggest advantage of these demonstrations is that the customer experiences the extremely low yield – that is the ultra-high diamond-by-weight concentrate – delivered by the sorter.

“This in turn highlights the significant downstream benefits with regards to hand sorting and security. What’s even more impressive for them to see is the exceptionally low amount of gangue ejected with the diamond concentrate, even for the difficult-to-sort ultra-fine size fractions.”

TOMRA has also demonstrated the COM XRT 300/FR sorter at the Electra Mining Show 2022, performing simulated operational production runs for the entire duration of the exhibition. The sorter was fed with fine alluvial ore, which had diamond dust tracers and diamonds added.

de Jager comments:

“This realistic and live operation drew a never-ending stream on show goers. The live demo show has resulted in numerous enquiries and sales. In fact, a ‘hands-on’ CEO of a large diamond operation had lengthy discussions with the TOMRA team on site. In front of the crowd, he asked us to process 1 kg of alluvial gravel and to include 150 diamond tracers and 10 diamonds. The sorter delivered a perfect result, ejecting all 160 added tracers and diamonds, with minimal ore particles. The crowd cheered, while the CEO shook hands with our TOMRA design specialist.”
