radiometric sorting uranium ores

Implications of integrating radiometric sorting in uranium

6/12/  · Radiometric 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 uranium ore

Jan 01, · Radiometric sorting trials at Ranger mine in Australia and Rössing in Namibia are reported by Schnell ( ), who also comments that “[G]ravity separation has been applied to uranium ores in the past with some success, but this was associated with radiation issues” (cf. Section , where it was used with very highgrade ore).

The development of a radiometric sorter for South African

1/1/1983 · Radiometric sorting of South African gold ores using uranium as a tracer has become practical and economical due to the introduction of microprocessors into the sorting machines. In the sorter, the particles are presented individually to the γ-ray counting and mass determination system.

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

X-ray luminescence (XRL) sensors for diamond sorting. Radiometric sensors for processing uranium ores. Electromagnetic (EM) sensors for separating minerals based on differences in their electrical conductivity or magnetic susceptibility. These are often used to improve the grade of nickel sulphide ores.

Beneficiation process for low grade uranium ores - URANIUM

For some run-of-mine uranium ores the grade and mineralogy are such that pre-leach treatment is limited to crushing and agglomeration for heap leaching, or crushing and wet grinding for conventional tank leaching. Radiometric sorting may be applied if appropriate.
