Ore grades have ranged from over 15% to less than % U. Various milling and purification methods have been developed, nearly always employing acid or alkaline leaching of uranium from crushed and ground ore followed by one or both of solvent extraction or ion exchange, used to purify and concentrate the uranium prior to precipitation and drying.

Uranium Ore (Carnotite). Milling: This process takes place at a mill after the ore containing uranium is removed from the Earth through open pit or underground ore is brought to a mill, crushed, and ground up before chemicals are added to dissolve the uranium. The uranium is then separated from the chemical solution, solidified, dried and packaged.
