Uranium Recovery (Extraction) Methods | NRC.gov

2020-12-2 · Uranium recovery involves one of the following extraction processes. In a conventional uranium mine and mill, uranium ore is extracted from the Earth, typically through deep underground shafts or shallow open pits. The ore is transported to a mill, where it is crushed and undergoes a chemical process to remove the uranium.
