URANIUM MINES Most uranium ore is mined in open pit or underground mines. The uranium content of the ore is often between only 0.1% and 0.2%. Therefore, large amounts of ore have to be mined to get at the uranium.
Uranium Mining and Milling Wastes: An Introduction. URANIUM MINES Most uranium ore is mined in open pit or underground mines. The uranium content of the ore is often between only 0.1% and 0.2%. Therefore, large amounts of ore have to be mined to get at the uranium. Get More Info.
This process brings the uranium-bearing solution to the surface, where the uranium is extracted. Conversion: From Yellowcake to Uranium Hexafluoride. Yellowcake requires further chemical processing before it's used as a fuel. A conversion plant removes impurities and converts the material to uranium hexafluoride, the form required for enrichment.
