Everything You Need to Know about How Uranium Is Mined

Feb 8, 2022The finely ground ore is placed in the process plant where it's treated with acid and the slurry is filtered to separate the metals. The uranium is purified by ion exchange. In this process, the uranium is stripped of other metals and then the uranium is put into a solution. When the uranium is stripped, it becomes uranium oxide or yellow cake.

Uranium is the primary element used in nuclear energy, one of the most important global energy sources. Since nuclear energy does not produce GHG emissions, it has gained popularity as an alternative energy source. Uranium must go through a refining process (mining, conversion, and enrichment) to become suitable for nuclear energy generation.

Uranium mining - Energy Education

Depending on the deposit, uranium is mined in one of three ways: [4] open pit, underground, or in situ recovery. Open pit When uranium is found near the surface - usually no more than 100 meters deep - it can be extracted via open pit mining. In this method, soil and waste rock is removed by heavy equipment, allowing the ore to be accessed.
