Process Of Mining Uranium

Uranium mining Wikipedia

Uranium mining is the process of extraction of uranium ore from the ground. The worldwide production of uranium in 2019 amounted to 53,656 tonnes. Kazakhstan, Canada, and Australia were the top three uranium producers, respectively, and together account for 68% of world production. Other countries producing more than 1,000 tonnes per year included Namibia, Niger, Russia, Uzbekistan, the United States, and China. Nearly all of the world's mined uranium is used to power nuclear power plants.

This ore treatment process, referred to as lixiviation, precedes the purification stage. The uranium is then extracted from the solution by a precipitation process before being purified, dried and calcined to result in a natural uranium concentrate: yellow cake, which contains 80% uranium (or 800 kg per ton).

In Situ Leach and Conventional Uranium-Recovery Methods

Jun 07, 2020 The ISL method involves these steps: A solution of oxygen, hydrogen peroxide, or another oxidizing agent in water is injected into an underground zone that bears uranium ore. In contact with this injection solution, the uranium dissolves. The injection solution containing the dissolved uranium is pumped back to the surface for uranium recovery.
