Radioactive Waste From Uranium Mining and Milling | US EPA

 · Uranium Ore (Carnotite). Milling: This process takes place at a mill after the ore containing uranium is removed from the Earth through open pit or underground ore is brought to a mill, crushed, and ground up before chemicals are added to dissolve the uranium. The uranium is then separated from the chemical solution, solidified, dried and packaged.

The Health and Environmental Impact of Uranium Mining

While the popularity of this method has declined since the 1980's, it is still in use in some plants today. [3] Underground mining requires drilling deep shafts into the ore bed. This technique employs water to prevent radiation exposure to laborers. [4] The ore deposits are brought to the surface and arranged in piles near the extraction points. Then, ore is processed into Uranium

Acid and ferric sulfate bioleaching of uranium ores: A

 · Uranium is usually finely disseminated in ore bodies, making leaching the most common process to recover it instead of ore dressing for concentrate production. Many uranium ores processed via bioleaching have contained significant amounts of pyrite and other Fe-sulfides, which are oxidized to acidic ferric sulfate. The hydrolysis of ferric iron in bioleach
