potential of the multi-sensor ore sorter is that underground mine production rates can be increased by 34% without any increase in process plant size. EganStreet Managing Director Marc Ducler said the application of ore-sorting technology represented a potential game-changer for the Rothsay Gold Project.

The effect of self-absorption is also a high-energy phenomenon in XRL. XRT is limited to sorting large size diamonds as the technique suffers poor contrast for diamonds smaller than 10mm. XRT measurements are immune to self-absorption for all sample sizes, while XRL measurements have good contrast for particles smaller than 32mm.

"The confirmation of XRT effectiveness at large scale is an important milestone in Ucore's march to mine construction," said McKenzie. "The company is the first in the rare earth industry to demonstrate XRT as a beneficiation technique; a technology already well-established in the tungsten and diamond mining sector.

Ore sorting test work and analysis on Main and Esso deposits, including a ¾ tonne bulk composite sample derived from drill core, was undertaken by ABH Engineering and TOMRA Sorting Solutions. This work demonstrated that ore sorting using an XRT (x-ray transmission) sensor would be cost-effective and is incorporated into the FS processing design.

· In July 2014 Thor published an updated ore reserve following the completion of a new mine plan by AVCS. The 2014 mine planning cycle was underpinned by the inclusion of an XRT ore sorting pre-concentration stage in the processing stream and incorporated revised operating and capital cost estimates and metal prices.

Sep 29, 2021Preliminary test work on the sensitivity of the ore to a XRF sensor was also undertaken." The bulk sample tests conducted on a production-scale XRT ore sorter indicate that approximately 17% of the ROM material will be <12.5 mm in size and would therefore bypass the ore sorter and report directly to the milling and flotation circuit.
