Uranium Mining and Milling Wastes: An Introduction
In the early years of uranium mining after World War II, the mining companies often left sites without any clean up after the ore deposits were exhausted: often, in the United States, the mining and milling facilities were not even demolished, not to mention reclamation of the wastes produced; in Canada, uranium mill tailings were often simply dumped in one of the numerous lakes.

Research in the uranium mining and milling industry continues for the placement, containment, and isolation of radioactivity in mine wastes to provide effective long-term containment without significant financial, health, or environmental liabilities placed on future generations.
Radioactive Waste and Uranium Mines - WorstPolluted.org
Uranium Mining and Processing Wastes are a special category of (normally) low level wastes, which are of major concern because of the volumes of radiating materials concentrated in usually a small area, thus creating an overall hazard. While uranium is mined around the world, some of the biggest producers are low-income countries.

Uranium tailings - Wikipedia
Uranium tailings are a waste byproduct of uranium mining. In mining, raw uranium ore is brought to the surface and crushed into a fine sand. The valuable uranium-bearing minerals are then removed via heap leaching with the use of acids or bases, and the remaining radioactive sludge, called "uranium tailings", is stored in huge impoundments.
Uranium in Tajikistan - World Nuclear Association
Uranium mining and milling. During the Soviet era, uranium ore mined in Tajikistan, Uzbekistan, and Kyrgyzstan was milled into yellowcake at Tajikistan’s Vostochnyy Rare Metal Industrial Association (Vostokredmet), previously known as the Leninabad Mining and stone Combine, in …

The conventional mining and processing of uranium and thorium ores generate large amounts of waste material. Mine operations generate overburden, barren waste rock and mineralized waste. Uranium and thorium mills process the mined material by milling and stone leaching, and typically produce a residual sand-like material

begins with the mining of low-grade uranium ore primarily from Canada, Australia, and Kazakhstan. It is milled, and crushed and treated with a solvent to concentrate the uranium. Milling produces yellow-cake, a material containing 70-90% uranium oxide
