Australia Yeelirrie

Australian Vanadium—Uranium Ore. A calcareous camotite ore at Yeelirrie, Australia, is ill-suited for salt roasting and acid leaching. Dissolution of vanadium and uranium by leaching in sodium carbonate solution at elevated temperature and pressure has been tested on a pilot-plant scale...

Surficial deposits comprise about 4% of world uranium resources, and such deposits represent 5% of Australia s total reserves and resources of uranium. They formed where uranium-rich granites were deeply weathered in a semi-arid to arid climate. The Yeelirrie deposit in Western Australia is by far the world s largest surficial deposit. 

Because of their ephemeral nature there are no known uraniferous calcretes older than about 300000 years.The known deposits contain, however, about 2.4% of the Western world s reasonably assured 30 uranium resources. The largest and best-known are those at Yeelirrie, Western Australia (believed to contain about 50000 ton UjOs), and Langer Heinrich, Namibia. Other occurrences are in these countries as well as in Angola, Botswana, Mauritania and Somalia.
