How is uranium made into nuclear fuel - World Nuclear ...

The vast majority of nuclear power reactors use the isotope uranium-235 as fuel; however, it only makes up 0.7% of the natural uranium mined and must therefore be increased through a process called enrichment. This increases the uranium-235 concentration from 0.7% to between 3% and 5%, which is the level used in most reactors.

Oct 26, 2009 · The theoretical grade-recovery curve for an ore is a definition of the maximum expected recovery by flotation of a mineral or element at a given grade. This is defined by the surface area liberation of the value minerals and is consequently directly related to the grind size utilised in the process. The theoretical grade-recovery can be readily used to quickly identify potential recovery ...
