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.

History. While uranium is used primarily for nuclear power, uranium mining had its roots in the production of radiumbearing ore from 1898 from the mining of uraniumvanadium sandstone deposits in western Colorado. The 1950s saw a boom in uranium mining in the western, spurred by the fortunes made by prospectors such as Charlie United States was the world's leading producer of ...

Since 2001, the uranium spot price has rapidly escalated to over 70 per pound (April 2008). This price increase resulted from a lack of uranium mine development over the past couple decades, compounded by the recent increases in demand. The new higher uranium price has encouraged renewed exploration and development in Utah and may lead to the ...

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.
