Jun 12, 2009Radiometric sorting has been integrated into the flowsheet as an ore enrichment process during the downturn in the uranium industry in the mid-1980s. This technique separates uranium ore from the waste rock, producing a uranium-rich beneficiated ore for subsequent processing in the hydrometallurgical circuit.

The evidence presented serves to demonstrate conclusively that the U/Pb system in this uranium deposit has been so open that it is impossible to be sure of the precise history of U and Pb in any sample selected for dating, making any age determinations meaningless.
