    Uranium mining is the process of extraction of uranium ore from the ground. The worldwide production of uranium in 2019 amounted to 53,656 tonnes. Kazakhstan, Canada, and Australia were the top three producers and together account for 68% of world uranium production. Other important uranium producing countries in excess of 1,000 tonnes per year were Namibia, Niger, Russia, Uzbekistan and China. Uranium from mining is used almost entirely as fuel for nuclear power plants.
