Orebodies lying less than about 500 feet below the surface are typically surface mined as it is much cheaper than underground mining. After extraction, the uranium ore is transported to a processing plant where it is milled. This process involves crushing the ore, chemically extracting the uranium, and concentrating it into yellowcake. Contact:

The Processing Plant is responsible for the extraction of uranium from mined ore through a number of stages to produce uranium oxide (U3O8). This product is securely packed and shipped to our customers for further conversion. The aim of the plant is to produce targeted quantities of uranium oxide in the most efficient and safe manner possible.

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

Uranium ore can be extracted through conventional mining in open pit and underground methods similar to those used for mining other metals. In-situ leach mining methods also are used to mine uranium in the United States.In this technology, uranium is leached from the in-place ore through an array of regularly spaced wells and is then recovered from the leach solution at a surface plant.
