Beneficiation - an overview ScienceDirect Topics

Peter H. Woods, in Uranium for Nuclear Power, 2016. 6.4.2 Ore beneficiation (including ablation, radiometric, and gravimetric sorting) Ore beneficiation refers to the selection and collection of higher-grade ore fragments or rejection of lower-grade fragments from ROM ore. The upgraded ore will have a higher grade, and therefore require a smaller-scale processing plant, perhaps with different

A very extensive range of uranium concentrations may be covered. Laser fluorimetry is suitable for direct determination of uranium in natural water systems within the μg L −1 and mg L −1 range while differential technique in laser fluorimetry (DT-LIF) is suitable for mineralized rocks and concentrates independent of matrix effects (uranium in samples containing >0.01% uranium).
