In-Situ Uranium Mining Process - Ur-Energy

The pump in the production well collects the uranium laden water and sends it to the processing plant where the uranium is removed by ion exchange. The water is then refortified with oxygen and baking soda and sent back to the ore zone to recover more uranium. The native groundwater continues in this cycle until uranium extraction is complete.

Nuclear Fuel Cycle Department of Energy

Milling produces a uranium oxide concentrate, which is shipped from the mill. In the milling process, uranium is extracted from the crushed and ground-up ore by leaching, in which either a strong acid or a strong alkaline solution is used to dissolve the uranium oxide. The uranium oxide is then precipitated and removed from the solution.

All three mining methods produce uranium suspended in liquid. The liquid is filtered and the uranium extracted from it by ion exchange to form a uranium oxide concentrate. This is a bright yellow powder, known as yellowcake. Yellowcake is only mildly reactive and must go through the enrichment process before uranium is usable in a commercial way.
