Solid bowl centrifuge FAQs
Solid bowl centrifuges allow to re-capture up to 90 per cent of the water, as the centrifuge separates the fine solids using G-forces from the contaminated process water. The solids are discharged as a cake with a low moisture content that can be dry-stacked, and used for mine rehabilitation in a similar fashion to overburden and coarse rejects.
Nuclear Fuel Cycle | Department of Energy
— The front end prepares uranium for use in nuclear reactors. These steps include mining, milling, conversion, enrichment, and fuel fabrication. The back end ensures that the used nuclear fuel is safely managed, recycled, or disposed of. These steps include fuel storage, recycling, and waste disposal. Uranium Mining
