This is being looked at by TOMRA in Germany and not factored into the project yet. Here is an example of how it can help -
ANOTHER COMPANY
The test work announced today is based on nine grab samples taken from historical tailings,waste-rock dumps, and drill core. These selective samples returned average grades of 0.15% tin,0.14% tungsten, and 0.3% copper. After ore sorting, the average grades increased significantly to1.1% tin, 1.02% tungsten, and 1.18% copper – representing average upgrades of 8x, 7x, and 4xrespectively. Perhaps most notably, a 90% mass reduction was achieved with minimal metal loss:the average reject material graded just 0.04% tin, 0.04% tungsten, and 0.18% copper. Overallrecoveries from the ore-sorting circuit averaged 72% tin, 74% tungsten, and 43% copper. Company highlight that the XRT ore sorting equipment used for the test work “demonstrated theability to effectively identify and separate multiple target elements simultaneously, confirming thepotential for a high-value polymetallic concentrate”.
Why is ore sorting significant? Ore sorting improves mining efficiency by separating valuablematerial from waste early in the process, which reduces the volume of ore that must be hauled,processed, and milled. It can enable lower‑grade deposits to become economically viable andmay allow smaller, more selective mining methods that minimise dilution and extend mine life. Inan already operating scenario, the introduction of ore sorting can increase capital costs, but theseare often outweighed by lower operating costs and reduced environmental impacts from reducedenergy use, water consumption, wear on processing circuits, and waste handling. Whenconsidered as part of new mine design ore sorting can reduce initial capital costs as downstreamprocessing equipment requirements are downsized.
