Thus, tailings are the original sand minus much of the uranium plus residual process chemicals. Tailings are less radioactive than the original ore uranium metal production in a conversion facility is done postenrichment.

Uranium Wikipedia

Uranium is a chemical element with symbol U and atomic number 92. It is a silverywhite metal in the actinide series of the periodic table. A uranium atom has 92 protons and 92 electrons, of which 6 are valence electrons. Uranium is weakly radioactive because all isotopes of uranium are unstable, with halflives varying
