Uranium Ore Carnotite Milling This process takes place at a mill after the ore containing uranium is removed from the Earth through open pit or underground mining.The ore is brought to a mill crushed and ground up before chemicals are added to dissolve the uranium The uranium is then separated from the chemical solution solidified dried and packaged.

uranium must be removed via a milling process The uranium ore is crushed and made into a slurry by mixing it with water The ore is then mixed with acid where like the In Situ process the uranium is separated from the other materials in tanks The now separated uranium can be dried and takes the common form of Uranium oxide or Yellowcake.
