    Cameco U101 Milling

    The milling process for uranium is similar to that used for other metals such as copper, gold or nickel. The first step is to crush the ore and mix it with water so that it can move through a series of mill circuits. After crushing, the ore is treated with acid in large tanks to separate the uranium from other minerals in the host rock.
