Quasar Resources Pty Ltd
In situ recovery (ISR) is the chemical process of extracting minerals from the host rock underground through the utilisation of specially designed wellfields. Where the ore exists in an underground aquifer, as is the case at Four Mile, oxygen and a weak acid mining solution is pumped through the ore body to dissolve the uranium minerals. The dissolved uranium is then pumped to the surface, where it is loaded onto resin at the Beverley North Pannikan plant before being transferred to the Beverley Processing Plant for further processing via the iron exchange (IX) process, dried and packaged for export.
|Location||550 km north of Adelaide, east of the northern Flinders Ranges (adjacent to the Beverley Uranium Mine).|
