World Uranium Mining - World Nuclear Association

Conventional mines have a mill where the ore is crushed, ground and then leached with sulfuric acid to dissolve the uranium oxides. At the mill of a conventional mine, or the treatment plant of an ISL operation, the uranium then separated by ion exchange before being dried and packed, usually as U 3 O 8.Some mills and ISL operations (especially in the USA) use carbonate leaching instead of ...
