TOMRA X-Ray Transmission (XRT) sorters provide a game-changing solution for the Mt Carbine mine in Queensland, Australia. On the one hand, they deliver remarkable cost savings while achieving high-purity Tungsten for the processing plant. On the other hand, they contribute to a circular economy by effectively eliminating contaminants from the waste rock, which is used to produce green aggregates for sale – also creating an additional revenue stream for owner EQ Resources.

Turkish Quartz mining company Mikroman Maden A.Ş, first adopted sensor-based sorting technology at three of its processing plants.
