Any metal in the impure anode which is below copper in the electrochemical series (reactivity series) does not go into solution as ions. It stays as a metal and falls to the bottom of the cell as an "anode sludge" together with any unreactive material left over from the ore. The anode sludge will contain valuable metals such as silver and gold.

Uranium Milling and Processing. Once the ore is mined, it is typically milled on site into a uranium oxide concentrate, often known as "yellowcake". 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. ...

Alternatively, uranium may be recovered from the ore using a heap leach process. In the heap leach process, the ore is placed on a engineered barrier and sprayed with acid. The uranium dissolves into solution and is collected at the engineered barrier. The solution undergoes additional chemical processing to produce "yellowcake".

Uranium ore is a resource found on the map. Instead of being smelted in a furnace, uranium ore must be processed in a centrifuge to produce uranium-235 and uranium-238, which is used to craft fuel for the nuclear reactor and in various types of ammunition..
