Uranium — How Is It Mined?

The uranium must be removed from the dirt by using strong acids yielding only 7-pounds of that as U-235. So, mining one million pounds of earth will yield only 7-pounds of U-235. Each nuclear reactor consumes hundreds of pounds of U-235 yearly, so mining enough uranium for the worlds' 450 nuclear reactors is a huge endeavor.
