Under nuclear fission with thermal neutrons uranium release an enormous quantity of energy (202,5 MeV per one atom of 235U); the obtained heat is converted in electricity.

Uranium ore is not...uranium ore !
Nuclear material for nuclear reactors are usually obtained from uranium. Uranium is obtained from uranium mines (open pit or underground mines) the same way mining for other minerals. Uranium then passes through different processes until getting it in a suitable form for fabrication into nuclear fuel.
1. Uranium must be refined to obtain "nuclear grade" uranium. 2. The enrichment in the isotope 235U depends on the type of the nuclear reactor; some reactors (as CANDU) work with natural uranium.
Uranium mined as an ore is the source of the fuel.
natural nuclear reactors are not possible now as the concentration of fissionable Uranium-235 in unenriched natural Uranium ore is too low.
We mine uranium for use as a nuclear fuel. The uranium is separated from ore, and may undergo enrichment to separate out the lighter U-235 nuclide from the heavier U-238 one.
An important ore of uranium is called Pitchblende.
The primary uranium ore mineral is uraninite (UO2) or pitchblende (UO3, U2O5), commonly collectively refered to as U3O8(the most stable form). A range of other uranium minerals can be found in various deposits.
