• Uranium Processing

    Milling. Uranium ore is crushed and processed in uranium mills, loed at or near the mines, to extract uranium using chemical processes. A fine powder, called "yellowcake", is the resulting uranium concentrate product and is packed in 55 gallon ringsealed drums containing approximately onehalf tonne of yellowcake. Mine tailings are ...

  • Is uranium ore dangerous?

    In and of itself, uranium bearing ores are not particularly dangerous. However depending on how it is mined, and the grade of the deposit, humans can be exposed to uranium's daughters, like radion. This was particularly true in older workings that were poorly ventilated. Modern open cast and in situ leaching does not expose workers.

    8 per year to keep a large (1000 MWe) nuclear reactor running; mining and milling uranium to feed such a plant would, therefore, emit t CO 2 each year. This is similar to the total CO 2 emission from the Falkland Islands in 2004. Exploiting uranium reserves suggests that these environmental costs will increase over time as high grade ore
