Mining Milling Conversion and Enrichment of Uranium

2011-12-3  Uranium as mined cannot be fed directly into a nuclear power station in contrast to coal, gas, or oil in a fossil-fueled power station. Uranium ore contains mineral and chemical impurities including radioactive daughter products of uranium. The uranium consists of 0.7% uranium-235 and 99.3% of uranium-238 isotopes.

2017-5-15  In situ leach (ISL) mining involves when uranium is in groundwater in porous unconsolidated material such as gravel or sand. In this state, uranium is accessed by dissolving it, and then pumping it out of the ground. The last type of uranium extraction is heap leaching. This type of extraction is generally utilized with very low-grad ore.

Uranium conversion and enrichment ScienceDirect

2020-1-1  Uranium conversion, which also incorporates uranium refining, is a necessary processing step for the production of nuclear fuel. The primary purpose of refining is to remove impurities from the uranium that could lead to deleterious effects during fuel manufacturing, enrichment, and irradiation in a nuclear power reactor.

Uranium mine and mill remediation and reclamation

2016-1-1  Acid mine drainage (AMD) is an important aspect of uranium mine/milling site rehabilitation (Merkel et al., 2002), as it is in other mining industries, where contained sulfides can oxidize and produce acidic solution. AMD results in an increased potential to mobilize impurities, including radionuclides of uranium, radium, thorium, and lead.
