RECOVERY OF URANIUM FROM ORES (Journal Article)

Uranium is recovered from an ore by forming, from the ore, a clear solution of a hexavalent uranyl-alkali metal or -ammonium carbonate solution, precipitating hydrated UO/sub 2/ from the solution by forming nascent hydrogen therein and separating this oxide. The nascent hydrogen is produced by subjecting the solution to electrolysis in the presence of a hydrogenation catalyst, e.g., Pt or Pd.

recory of uranium from uranium ores - gieterijneede. Uranium Ore. With the decreased market price of uranium beginning in the 1980s, U.S. producers turned increasingly to in-situ recovery (ISR) operations to extract uranium from ore. In-situ recovery (also known as "solution mining") is when fluids are injected into an ore-bearing aquifer to mobilize uranium, which becomes soluble in water ...

In Situ Recovery Uranium Producers of America

Uranium decays into radium and radon gas, and other “daughter” products. Over hundreds of thousands, or millions, of years, these decay products build up and contaminate the water in and near the ore body. For example, the U.S. EPA has a proposed maximum level for radon gas of 300 pCi/L in drinking water. In a uranium orebody, it is common ...
