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
Milling and processing. Conventional mines have a mill where the ore is crushed and ground to liberate the mineral particles, then leached in tanks with sulfuric acid to dissolve the uranium oxides. The solution is then processed to recover the uranium. With some South African uranium recovery from gold tailings, a pressure leach is necessary.
