The most common ore of the element is pitchblende, although it is also present in other minerals, such as uraninite, carnotite, uranophane, and coffinite. |
But couldn't the carnotite have been stolen from a privately owned mine? |
But it seems to be pulverized ore, and my guess would be carnotite. |
Pitchblende is the best, but carnotite, which is a gray rock with yellowish streaks, is also good ore. |
Tyuyamunite is closely related to carnotite as indicated by the chemical formula. |
It is found in a number of minerals, including vanadinite, carnotite, roscoelite, and patronite. |
