  • Uranium How is it Mined

    Milling. For both traditional underground and open pit mining the rocks may have only a few percent (normally <0.3 ) uranium in them. The uranium then has to be removed from the rock and concentrated. The milling process involves crushing and pulverizing the rock into very fine fragments and adding water to create a slurry.
