Implications of integrating radiometric sorting in uranium

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.

RADIOMETRIC SORTING REPORTS POSITIVE RESULTS

RADIOMETRIC SORTING Radiometric sorting is a simple technique that uses the primary physical characteristic of the ore (radioactivity due to the presence of uranium) to divide the sample into two portions: a radioactive portion (the accept fraction) and a non‐radioactive portion (the reject fraction).

Summary. The results have been obtained on the basis of the assumption that the U/Pb system must have always been closed. 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.
