How is uraninite formed?
Uraninite often forms when hydrothermal circulation picks up uranium from a uranium-rich rock (such as granite or syenite) and concentrates this uranium in a hydrothermal ore deposit. The primary reason that uraninite is mined is to provide fuel for nuclear power plants. Uranium can be found in almost all rocks.
What is the streak of uraninite?
Brownish black
Radioactive decay of the uranium causes the mineral to contain oxides of lead and trace amounts of helium….
| Uraninite | |
|---|---|
| Streak | Brownish black, gray, olive-green |
| Diaphaneity | Opaque; transparent in thin fragments |
| Specific gravity | 10.63–10.95; decreases on oxidation |
| Optical properties | Isotropic |
Which is known as yellow cake?
Yellowcake (also called urania) is a type of uranium concentrate powder obtained from leach solutions, in an intermediate step in the processing of uranium ores. It is a step in the processing of uranium after it has been mined but before fuel fabrication or uranium enrichment.
Who invented pitchblende?
Three chemical elements were first discovered in pitchblende: uranium by the German chemist Martin Klaproth in 1789, and polonium and radium by the French scientists Pierre and Marie Curie in 1898.
What type of mineral is uraninite?
uraninite, a major ore mineral of uranium, uranium dioxide (UO2). Uraninite usually forms black, gray, or brown crystals that are moderately hard and generally opaque. A variety of uraninite ore that is dense and found in granular masses with a greasy lustre is called pitchblende.
What are uraninite used for?
Uraninite is a naturally occurring uranium oxide. Highly radioactive and unstable, its primary use is in the production of uranium reactor rods for nuclear generators.

What can I do with uraninite?
Uraninite Crystals are a raw material used to create a single component, the Reactor Rod (Subnautica). They can be found both in raw form on the seabed and as a large resource deposit.
