Yeah, saw those figure wrt the other thread and wondered how many tons of non-uranium are mined in order to extract the uranium. I decided I didn't know enough about uranium mineral deposition to come to a reasonable analysis and couldn't readily find such information. Is uranium ore found in large seams like coal?

Others following one of my other comment have basically said that in situ leeching is the only method used but I doubt that for several reasons. Not least of which that I gathered uranium is mined alongside other metals and I doubted acid leeching would work for all of them at the same time.
