Flow Diagram Uranium Milling

Water Treatment for Uranium at DOE's the U

At a former uranium milling site near Tuba City, Arizona, uranium-contaminated ground water is pumped from extraction wells and treated by ion exchange followed by distillation. The average flow rate is about 340 lpm, and the influent uranium concentration is about 250 µg/L. About 40 kg of uranium is removed from the aquifer per year.

Nuclear Fuel Cycle Overview - World Nuclear Association

The uranium oxide product of a uranium mill is not directly usable as fuel for a nuclear reactor – additional processing is required. Only 0.7% of natural uranium is 'fissile', or capable of undergoing fission, the process by which energy is produced in a nuclear reactor. The form (or isotope) of uranium which is fissile is uranium-235 (U-235).
