  • Tenorm Uranium Mining Residuals Radiation

    With the decreased market price of uranium beginning in the 1980s, u.Producers turned increasingly to in-situ recovery isr operations to extract uranium from ore.In-situ recovery also known as solution mining is when fluids are injected into an ore-bearing aquifer to mobilize uranium, which becomes soluble in water.

  • Why Is It So Expensive To Purify Plutonium Or Enrich

    The reason why uranium enrichment is expensive is because the separation of u-235 from u-238 is based on a tiny difference in mass between compounds of the two isotopess.Enrichment using centrifuges requires a compound in the gas phase.
