Environmental and Health Impacts of Uranium Mines. Uranium mining facilities produce tailings that generally are disposed of in near surface impoundments close to the mine. These tailings pose serious environmental …

Ore mined in open pit or underground mines is crushed and leached in a uranium mill. A uranium mill is a chemical plant designed to extract uranium from ore. It is usually located near the mines to limit transportation. In the most cases, sulfuric acid is used as the leaching agent, but alkaline leaching is also used.

• Uranium mining, processing, and reclamation have the potential to affect surface water quality and quantity groundwater quality and quantity, soils, air quality, and biota. • Significant potential environmental risks are associated with extreme natural events and failures in management practices.

Most US uranium-producing states are 'agreement states' vis a vis the Nuclear Regulatory Commission (NRC) and have authority to issue permits and regulate uranium mining and milling. The NRC's role is then minimal. In February 2015 Wyoming, the major uranium production state, passed legislation to make it an agreement state, along with all the other uranium-producing …

As with other types of hard rock mining there are several methods of extraction. In case of uranium mining, it strongly depends on the concentration of uranium in the ore. For example, the ore extracted from the Australian Olympic Dam Mine has a concentration of 0.05 %. Most reserves have uranium with a concentration of between 0.1 bis 0.2 %.
