Uranium mining (open cut and underground) and milling

Abstract. Uranium has been mined since about 1830 as a glass and glaze colorant, but its exploitation began in earnest in the 1940s, initially for military purposes but then from the mid-1950s for fuel for nuclear power plants. Mining from underground and open cut mines has dominated production. Ore grades have ranged from over 15% to …

Uranium Mining

Uranium mining and milling is the starting process for all nuclear fuel cycles. In this process, uranium ore is extracted from the Earth's crust, similar to copper, ... Uranium-loaded resins are then transported to a processing plant, where U 3 O 8 is separated from the resin beads, and a yellowcake is produced. The ISL method can be used ...

Nuclear Fuel Cycle Overview

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).

A raised uranium ore slurry pipe connects the crushing and grinding mill, located adjacent to Mine 1, to the plant. Satellite imagery offers few observable indicators of the plant's operational status. Dust and chemical stains around the roof vents of a number of the buildings reveal use but change little between coverage.

Environmental and Health Impact Due to Uranium Mining

A 75-fold higher uranium concentration has been found in the vegetation near to the milling plants in New Mexico. Although a daily intake of uranium in food and water varies from 1 to 5 μg U d −1 in the uncontaminated areas, the intake is usually above 13 μg U d −1 nearer to uranium mining area.

Uranium Mining and Milling

Uranium is a naturally occurring radioactive element used for fuel in nuclear power reactors. Canada, one of the world's largest uranium producers, accounts for 18 percent of global production and exports 90 percent of its uranium.
