Uranium Recovery (Extraction) Methods NRC.gov

Dec 02, 2020  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.

Uranium Fuel Cycle EME 444: Global Energy Enterprise

The process of separating the uranium from the ore is called milling. In this process, the ore is crushed and mixed with an acid (typically) that dissolves the uranium out of the ore. This solution is separated out and dried, leaving a powder called "yellowcake." In addition to yellowcake, uranium recovery operations generate waste products ...
