TOMRA's X-ray Transmission (XRT) sorting technology allows mines to convert waste rock into a low-sulphide waste stream for reuse or sale as aggregate. EQ Resources at the Mt Carbine tungsten operation in Queensland, Australia, reports an annual revenue increase of A$5 million (US$3.5 million) from this method.

The approach also reduces environmental risks and creates opportunities for on-site infrastructure use. Wolfram Bergbau Mittersill in Austria similarly utilizes waste material for infrastructure and sales, with up to 40% of mined material classified as coarse waste.
