Carnotite is a bright yellow-green mineral that is primarily composed of potassium, uranium, and vanadium. It is classified as a member of the uranium mineral group and is often found in sedimentary rocks, particularly in areas with volcanic activity. Carnotite is an important source of uranium for nuclear energy production and is also used in the extraction of vanadium. This mineral typically forms in arid environments and can be found in places like the Colorado Plateau in the United States. Due to its radioactive properties, handling carnotite requires caution, and it is often studied for its potential environmental impacts and uses in nuclear technology.
