Uranium - an overview | ScienceDirect Topics

Uranium at less than 1 wt% is leached from uranium bearing ores by either acidic or basic processes to produce a pure uranium oxide product. For use in nuclear applications, the radioactive 235 U isotope, which comprises 0.7 wt% of natural uranium, is separated from 238 U by diffusion or centrifuging after conversion to the hexafluoride.
