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 ...

A conventional uranium mill is a chemical plant that extracts uranium using the following process: Trucks deliver uranium ore to the mill, where it is crushed into smaller particles before being extracted (or leached). In most cases, sulfuric acid is the leaching agent, but alkaline solutions can also be used to leach the uranium from the ore.

Processing Sites Congress designated 22 inactive uraniumore processing sites for remediation under Title I of UMTRCA in 1978. Many of these sites were abandoned when UMTRCA was passed. Remediation of the 22 sites resulted in the creation of 19 engineered disposal cells that contain uranium mill tailings and associated contaminated material.

The vast majority of nuclear power reactors use the isotope uranium235 as fuel; however, it only makes up % of the natural uranium mined and must therefore be increased through a process called enrichment. This increases the uranium235 concentration from % to between 3% and 5%, which is the level used in most reactors.
