Uranium mining, a significant industry in California, primarily includes companies that excavate, process, and sell uranium— a critical element required for nuclear power generation and military applications. These companies, ranging from large-scale mining corporations to investment firms, essentially fuel the nuclear power industry and provide financial backing to smaller-scale miners. As sustainability becomes paramount, uranium holds massive potential as a clean energy source, indicating a promising trajectory for the sector.
