Uranium mining - Energy Education

Uranium mining is the process of retrieving uranium from deposits for use in nuclear reactors to generate electricity.Uranium is also used for the important task of producing medical isotopes.. Uranium is not a rare element on Earth, occurring in 2.8 parts per million in the Earth's crust, and occurs in fairly large quantities in various geological settings.

Radioactive Waste From Uranium Mining and Milling | US EPA

Uranium Ore (Carnotite). 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 Overview - World Nuclear Association

Ore mined in open pit or underground mines is crushed and leached in a uranium mill. A uranium mill is a chemical plant designed to extract uranium from ore. It is usually located near the mines to limit transportation. In the most cases, sulfuric acid is used as the leaching agent, but alkaline leaching is also used.
