Why is purifying uranium so hard askscience

Sep 05 2008 0183 32 But for uranium uranium-238 is 238/235 times more massive than uranium-235 which is only about a 1 difference To make matters worse or better depending on which side you re on it s not elemental uranium which is being separated it s uranium hexafluoride gas So you re really separating gas molecules with a mass ratio of 352/349...
