    Top Uranium Producing Countries In The World

    Apr 25, 2017 · Uranium can also dissolve in hydrochloric and nitric acid and can also react with cold water when finely divided. When exposed to air, a layer of uranium oxide will coat the metal. Uranium is extracted as an ore by open pit, underground, or borehole mining methods. The ore is crushed into fine powders and then leached to form yellowcake.
