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).

Radiometric sorting is applicable to certain deposits particularly where the radioactive mineralized ore is sufficiently liberated from low-grade material and gangue. During the 1980s, radiometric sorting was incorporated into a number of plants and more recently Rossing Uranium (Namibia) has installed a demonstration plant. Leaching

Uranium Mine Feasibility Calculator HELP
Introduction This calculator performs calculations of the material and cost balance of uranium mine and mill operations. The calculator uses the following assumptions: the uranium ore is mined in an open pit or underground mine; then, the ore is sorted in a radiometric sorting process; and finally, the post sorting ore is processed in a uranium mill for uranium extraction in the form of U 3 O

The age of Australian Uranium Answers in Genesis
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.

Mar 10, 2016Bulk ore sorting could also be used to separate ore types to treat via different process routes, or to reduce dilution and ore loss in mining operations by improving grade control. It is an efficient way to deal with uncertainties of grade, particularly where the complexity of mine geology makes the estimation of grade difficult.
