recoverable uranium, it is necessary to process from 500 to 5000 kg ore for each kilogram of uranium recovered. To produce the same amount of uranium, therefore, millsize can vary by a factor of 10. Most uranium mills use wet grinding, and the resulting slurry is fed to a leaching circuit where sulphuric acid is added.

The alternative, 'dry' process is used in the USA. In the dry process, uranium oxide concentrates are first calcined (heated strongly) to drive off some impurities, then agglomerated and crushed. At Converdyn's US conversion plant, U 3 O 8 is first made into impure UF 6 and this is then refined in a twostage distillation process.

Radiation Facts. Regardless of how uranium is removed from rock, the extraction process creates radioactive wastes. If not managed properly, mining waste and mill tailings can contaminate the environment. Uranium is a naturallyoccurring radioactive element that has been mined and used for its chemical properties for more than a thousand years.
