Processing El Sherana Uranium ore at moline
Shown is a photo of a worker ‘settling’ the Uranium ore concentrate into an appropriate steel container in a well-ventilated area. United Uranium N.L., Moline, Northern Territory, 1963. (Photo courtesy of J. Taylor)
The light colour of the product shown in the photo is indicative of Ammonium Uranyl Carbonate (AUC), commonly known as yellow-cake. An alternative compound supplied to the Nuclear Energy Industry is called AUD which is an abbreviation for Ammonium Diuranate, (NH4)2U2O7. AUD is much darker in colour than AUC with a greenish brown hue. For a detailed discussion on the solvent extraction of Uranium from Uranium ores see Ullmann’s Encyclopedia of Industrial Chemistry, 40 Volume Set, 7th Edition, Section U, Uranium, Uranium Alloys, and Uranium Compounds; ISBN: 978-3-527-32943-4.
