Uranium processing - Canadian Nuclear Association

After crushing, the ore is treated with acid in large tanks, to separate the uranium from other minerals in the rock. The uranium is now part of a liquid solution, which is then separated from the other minerals, which remain solid. The uranium-rich solution is then purified through a solvent extraction process and solidified.
