   Mining and Milling
   Natural uranium, primarily composed of non-fissile $\text{U}-238$ (approx. 99.3%) and fissile $\text{U}-235$ (approx. 0.7%), is extracted from ores. These ores are subsequently milled to produce uranium concentrate, commonly referred to as "yellowcake" ($\text{U}3\text{O}8$). The geological consistency of uranium deposits exhibits high variability; for instance, the average $\text{U}3\text{O}8$ concentration in the terrestrial mantle sediments of the [Permian Basin](/entr…
