The uranium mill tailings, the waste by-product created during uranium extraction from the ore, posed concern because of the radioactive nature of the tailings and the additional chemicals used for extraction. At first, like many earlier waste practices, tailings were handled in a way that put the environment and humans at risk.

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].

Uranium Milling Process. After extraction, the ores from both open pit and underground mines require milling. Machines crush and pulverize the rocks into fine fragments. Processors first add water and then sulfuric acid or an alkaline solution to release uranium from the rocks. This produces uranium oxide (or yellow cake).

Uranium ores are normally processed by grinding the ore materials to a uniform particle size and then treating the ore to extract the uranium by chemical leaching. A conventional uranium mill is a chemical plant, usually built near the uranium mine. Uranium milling extracts uranium using the following process: Milling. Trucks deliver uranium

Milling, which is generally carried out close to a uranium mine, extracts the uranium from the ore. Most mining facilities include a mill, although where mines are close together, one mill may process the ore from several mines. Milling produces a uranium oxide concentrate which is shipped from the mill.
