The US Nuclear Regulatory Commission (NRC) accepted Disa's application for a licence to use its technology to remediate abandoned mine waste at inactive mine sites in April, when the regulator set a schedule for a detailed technical review and developed and deployed a clear, first-of-its-kind regulatory framework which saw the licensing approval process completed in six months - much quicker than the 18-24 months it might have taken previously.
Disa's patented High-Pressure Slurry Ablation (HPSA) technology is a mechanical process leveraging collisions between particles. It exploits the difference in Mohs hardness - a scale for measuring the relative hardness of minerals - between a base mineral and target mineral to selectively liberate the target mineral. The process can be used to upgrade critical minerals from both mined ore and legacy waste.
