Uranium mining - Wikipedia

Uranium from mining is used almost entirely as fuel for nuclear power plants. Uranium ores are normally processed by grinding the ore materials to a uniform particle size and then treating the ore to extract the uranium by chemical leaching. The milling process commonly yields dry powder-form material consisting of natural.

Nuclear fuel cycle - Wikipedia

For use in most reactors U3O8 is usually converted to Uranium hexafluoride (UF6), the input stock for most commercial uranium enrichment facilities. A solid at room temperature, uranium hexafluoride becomes gaseous at 57 °C (134 °F). At this stage of the cycle the uranium hexafluoride conversion product still has the.
