Uranium mining (open cut and underground) and milling ...
Uranium ore concentrate (UOC) is a general term to describe the final product of uranium mining and milling, although the term “yellowcake” is still loosely used. In fact, UOC may be yellow (eg, ammonium diuranate, uranyl peroxide), dark green-black, grey (U 3 O 8), , and sometimes orange. Download : Download full-size image; Figure 6.8.
Uranium Mining Overview - World Nuclear Association
Mill chemistry. The crushed and ground ore, or the underground ore in the case of ISL mining, is leached with sulfuric acid: UO 3 + 2H + ====> UO 2 2+ + H 2 O UO 2 2+ + 3SO 4 2-====> UO 2 (SO 4) 3 4-. The UO 2 is oxidised to UO 3.. With some ores, carbonate leaching is used to form a soluble uranyl tricarbonate ion: UO 2 (CO 3) 3 4-.This can then be precipitated with an alkali, e.g. as sodium ...

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.
