Uranium: How is it Mined?

The milling process involves crushing and pulverizing the rock into very fine fragments and adding water to create a slurry. This slurry is then mixed with sulfuric acid or an alkaline solution to release the uranium from the host rock. Normally approximately 95 - 98% of the uranium can be recovered from the host rock.

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,

Uranium Radiation Properties

Chemical separation of uranium (e.g. in a uranium mill) removes the decay products, while the isotopic composition of the uranium remains unchanged. However, within a few months, the short-lived decay products Th-234, Pa-234m, and Th-231 grow in, again. So, in most practical situations, their presence has to be taken into account, as well.

Dec 02, 2020  The gaseous diffusion process uses molecular diffusion to separate a gas from a two-gas mixture. The isotopic separation is accomplished by diffusing uranium [which has been combined with fluorine to form uranium hexafluoride (UF 6) gas] through a porous membrane (barrier), and using the different molecular velocities of the two isotopes to achieve separation.
