Ore beneficiation is the extraction of higher grade fraction from the mined uranium ore, by physical means such as kinetic processing and/or sorting. It is used for low-grade uranium ore to considerably reduce the amount of material that has to be processed in a uranium mill, while losing only a minor fraction of the contained uranium.
