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’s holistic approach and cutting-edge technologies can deliver consistent recovery rates, significant cost savings, operational advantages and a smaller environmental footprint.
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 give diamond operators the opportunity to experience first-hand the unique benefits of the 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 HMI (Human Machine Interface) panel.
“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,” TOMRA Mining diamond segment manager Corné de Jager said.
“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.
“This realistic and live operation drew a never-ending stream on show goers,” de Jager said. “The live demo show has resulted in numerous enquiries and sales.”
