Milling and Processing - How Uranium Mining Works ...

At the mill, uranium ore undergoes a variety of changes to turn it into a finished product: uranium powder, also known as yellowcake.. The milling process is so important that the U.S. Atomic Energy Commission has helped mines establish mills close by to make it easier to process uranium ore and quicken the production of yellowcake [source: Amundson].

Mining uranium: how safe is it and why do it? Myths and ...

2020-11-4  Indeed, today the uranium mining process's impact on the environment is minimal. After mining, the involved territory is reclaimed (of course, if needed; with a forest sitting on the surface and during mining, the need disappears altogether). Reclamation takes place most effectively using the underground leaching method.
