 hydrated copper uranate phosphate mineral, Cu(UO2)2(PO4)2·8–12H2O, that is one of the principal uranium-bearing minerals. Usually associated with autunite, it occurs as green crystals or micalike masses that are weathering products of uraninite. Torbernite is abundant in Cornwall, Eng., and in Katanga province, Congo (Kinshasa). For detailed physical properties, see phosphate mineral (table).
