Uranium Milling and Processing. Once the ore is mined, it is typically milled on site into a uranium oxide concentrate, often known as "yellowcake". In the milling process, uranium is extracted from the crushed and ground-up ore by …

Uranium Mining and Milling

Uranium is mined so it can be processed at a milling facility in order to recover the uranium concentrate. The uranium concentrate is then shipped to processing and fabrication facilities that create fuel for nuclear power reactors.

In Situ Recovery Facilities | NRC.gov

In situ recovery is one of the two primary extraction methods that are currently used to obtain uranium from underground. ISR facilities recover uranium from low-grade ores where other mining and milling methods may be too expensive or environmentally disruptive. This method uses the following process, as illustrated in the figure to the right:

Uranium Mining and Extraction from Ore

Uranium leaching is the process by which the uranium is extracted from the raw ore by reacting the material with acid or base. Fig. 2 shows a general process flow for the uranium extraction process. Prior to the leaching process, the ore is often given preliminary treatments that can include roasting and grinding.

Utah has the last conventional uranium mill in the country.

What happens to the waste after the uranium has been leached out? The chemical process that leeches uranium out of crushed ore produces sandy waste, called tailings, which both the Nuclear Regulatory Commission and the Environmental Protection Agency explain are radioactive. The mill's tailings are stored at the site in containment ponds.

Uranium Mining and Milling near Rifle, Colorado

The mill was left abandoned along with several million tons of unprocessed ore. In 1946, the plant was torn down and a new one built on the site to recover uranium. Vanadium is still used in the process of hardening steel. Additional ores were mined and milled for the uranium content from other sites in Colorado.
