TOMRA’s latest sorter showcased at Electra Mining

“ A side from TOMRA’s live demonstrations of the COM XRT 300 /FR at its Hamburg and Johannesburg offices, we recently show cased the product at Electra Mining Africa 2022. This is the first time that TOMRA has brought its revolutionary final recovery sorter to an exhibition and undertaken live demonstrations with ore, dia monds and diamond tracers. The aim was to give customers an opportunity to experience the sorter’s unique benefits. The demonstrations attracted large numbers of attendees, who were intrigued by the easy-to-handle, compact machine, which is able to recover more than 99% of diamonds, with a very small amount of gangue, from large quantities of ore.” TOMRA’s latest sorter completes TOMRA’s dia mond recovery solution as it now offers a full X-Ray transmission (XRT) technology solution range to sort particles in bulk concentrations from +4-100 mm, with the larger XRT sorters, to +2-32 mm particles in a final recovery or sort house application. The COM XRT 300 /FR sorter is especially handy for small capacity explorers looking for a compact machine. “Electra Mining 2022 was an extremely well attended event with the number of visitors from South Africa and abroad far exceeding our expec tations. We engaged with numerous visitors and TOMRA is grateful for the phenomenal feedback on our high efficiency product, which delivers extremely low amounts of gangue in the diamond concentrate. In fact, we received serious interest in the product with numerous follow-up requests. We look forward to turning these into product sales and successful installations,” she said. Advantages of the TOMRA COM XRT 300 /FR sorter TOMRA’s latest sorter is extremely competitive in terms of its capabilities and pricing, and it pro vides a high level of accuracy. It replaces multiple Sensor-based sorting technology special ist, TOMRA Mining, recently showcased its compact COM XRT 300 /FR final recovery sorter at Electra Mining Africa 2022. The product was launched to the market late last year. Modern Mining spoke to TOMRA Mining diamond segment manager, Corné de Jager about the mining industry’s inter est in its latest technology.

conventional sorting stages with a single machine. According to De Jager, the X-Ray camera which uses DUOLINE® sensor technology focuses on a single, constant property of the material – atomic density – hence detecting any type of diamond, irre spective of its coating or luminescence profile. The efficient alignment of the x-ray source, ultra-high res olution sensor technology and fine nozzles results in an ultra-high diamond by weight concentrate and a guaranteed > 99% diamond recovery. “If capacity requirements allow, single-feed batch processing of various size fractions vía a single unit is possible as the unit is supplied with various size frac tions programs within its sorting range of 2-32 mm. Secondly, the unit can easily be repurposed and/or relocated for a different size fraction within this size
