Mulga Rock Uranium Project

The mine is expected to yield 4.5Mt of ore a year and produce 1,360t of uranium oxide concentrate (UOC) a year, on an average, over its life time. The ore will be processed in two stages, once at the beneficiation plant and then at the main process plant. Run-of-mine (ROM) ore feed will be crushed and conveyed to a semi-mobile beneficiation plant.

7 Ways to Enrich Uranium

Mar 29, 2019These ions can be isolated to enrich uranium. This method was used to process uranium for the atomic bomb dropped on Hiroshima in 1945 and was also the enrichment method Iraq used in its nuclear weapons program of 1992. It requires 10 times more energy than gaseous diffusion, making it impractical for large-scale enrichment programs.

Is uranium mining good or bad? – Sidmartinbio

Mar 03, 2021Although uranium itself is barely radioactive, the ore which is mined must be regarded as potentially hazardous due to uranium's decay products, especially if it is high-grade ore. The gamma radiation comes principally from isotopes of bismuth and lead in the uranium decay series.
