  • Uranium and its applications Zeus Resources

    Uranium also occurs in seawater, with seawater estimated to contain an average of .003 ppm, and can be recovered from the oceans. Uranium ore can be mined by underground or open-cut methods, depending on its depth. After mining, the ore is crushed and ground. It is then treated with acid to dissolve the uranium, which is recovered from solution.
