Milling and Processing - How Uranium Mining …
After milling, other companies will buy the uranium to enrich it, or increase the ratio of the isotope U-235 in a given sample. During enrichment, scientists convert the yellowcake (uranium oxide) to uranium hexafluoride gas, which is put in cylinders to become a solid when it cools [source: NRC]. To enrich uranium enough to be used as nuclear fuel, workers will increase the concentration of U ...

Uranium mining and milling is the starting process for all nuclear fuel cycles. In this process uranium ore is extracted from the Earth’s crust similarly as for mining of copper, zinc, and other metals. Uranium is often found with copper, phosphates, and other minerals; thus, it is often a co-product of other mining operations. The worldwide production of uranium in 2015 amounted to 60496 ...
