Educational Video - Uranium: Born of the Stars

After mining, the ore is taken by trucks to a mill facility, where it is ground and crushed before being leeched in large tanks. The resulting solution is then taken through a number of refining steps which eventually end in drying the finished product into yellowcake and packing it into drums.

Uranium Mining | Atomic Heritage Foundation

Uranium milling is the process by which uranium ore is separated from other minerals, yielding dry-product referred to as "yellowcake." No matter which process is used for milling, large amounts of water are used to dissolve other minerals and keep the uranium particles from floating away.

Radioactive Waste From Uranium Mining and Milling | US …

Milling: This process takes place at a mill after the ore containing uranium is removed from the Earth through open pit or underground mining. The ore is brought to a mill, crushed, and ground up before chemicals are added to dissolve the uranium. The uranium is then separated from the chemical solution, solidified, dried and packaged.

Uranium mining in Utah, a state of the United States, has a history going back more than 100 years. Uranium mining started as a byproduct of vanadium mining about 1900, became a byproduct of radium mining about 1910, then back to a byproduct of vanadium when the radium price fell in the 1920s. Utah saw a uranium boom in the late 1940s and early 1950s, but uranium mining declined in the 1980s.
