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.

The Importance of Conventional Uranium Mills

The Extraction Process. Uranium ore is brought to the mill via covered trucks. The ore is unloaded into a grizzly hopper, where the ore is crushed into small grains. The crushed ore then flows through a series of leach tanks filled with sulfuric acid where the UO 3 found in ore is converted to UO 2 (SO 4) 3 4. [3] The acid acts as an electron
