Uranium tailings are differentiated from other types of tailings due to the radioactive nature of the material.
Radioactive tailings facilities pose long term hazards relating to both exposure and dam failure, with the
principal concern being the potential harm to both operator and Read more... about Management of Uranium Tailings

Palaeo-river channels containing calcrete are important potential hosts for economic uranium mineralization in many parts of southern Africa particularly Namibia. The main feature of these deposits are the dominance of the mineral Carnotite [K2(UO2)2(VO4)2.3(H2O)] as the main uranium host in Read more... about Geochemical controls on uranium precipitation
