I have seen a video of it in action. Gold a challenging mineral that the technology being applied to only in recent times (i think) due to advances in computing power and scanning technology.
Tomra website advises...
"Experience of applying sensor-based ore sorting in several mines has proved how critical/important the geological approach is to investigating and understanding the sorting feasibility of complex ores, and gold ore in particular. This is because, although the focus is not on gold detection itself, the correlations between detectable characteristics and gold content need to be present, well-understood and reliable in order to discern how gold deportation into product and waste fractions can best be achieved."
" The practical application of this technology in several mines has demonstrated how vitally important the geological approach is to exploring the sorting feasibility of complex ores such as gold."
I wonder whether ega have undertaken the preliminary steps to know that they will in fact be able to achieve the recovery they are estimating at Rothsay.
