I asked this in the last asteroid mining thread:

How do you get mining quantities ( ie hundreds or thousands of tonnes of minerals) from space to Earth and make sure they land in the right place, don't land too hard etc?
unguided, it would be fricking hard...

in order to nudge an asteroid to make it fall you earth you would need to

1. have it enter the atmosphere in a controlled manner so that is doesn't burn up
2. make it land somewhere very specific
3. recover it efficiently
4. refine and process the material
